What are the different classifications of titanium alloys?

By utilizing the different characteristics of the two structures mentioned above, titanium alloys with different microstructures are obtained by adding appropriate alloying elements to gradually change the phase transformation temperature and phase content. At room temperature, titanium alloys have three basic matrix structures, and titanium alloys are divided into the following three categories: α alloys, (α+β) alloys, and β alloys. China represents them as TA, TC, and TB respectively. It is a single-phase alloy composed of an α-phase solid solution. Whether at normal temperature or at higher practical application temperatures, it is always in the α phase, with stable microstructure, higher wear resistance than pure titanium, and strong oxidation resistance. At 500℃～

Analysis of the titanium application in China's chemical industry

In the coming years, the mainland China titanium market for chemical applications will continue to dominate the mainland China titanium market, with very broad prospects. In the past nine years, the amount of titanium used in mainland China's chemical industry has been approximately 70,000 tons, slightly higher than the sum of mainland China's titanium production in 2009 and 2010. According to him, the main applications of titanium in China's chemical industry include chlor-alkali, soda ash, vacuum salt making, petrochemical fibers, fine chemicals, and inorganic salts. The main user of titanium in the chemical industry is the chlor-alkali industry, where titanium equipment and pipes account for almost a quarter of its weight. Based on a calculation of approximately 6 tons of titanium used per 10,000-ton unit, the projected new production capacity of ion-membrane caustic soda in 2011 is 6 million tons, with an estimated titanium consumption of 36 million tons. The projected increase in production capacity in 2012 is 200 tons, with a titanium consumption of 1,200 tons.

The wonders of titanium

Titanium's remarkable properties are primarily demonstrated in its behavior at ultra-low temperatures, where it becomes even harder and exhibits superconducting properties, unlike steel which becomes brittle and ineffective. Its specific gravity is only half that of iron, yet it withstands hammering and drawing like copper. Titanium possesses strong resistance to acid and alkali corrosion; it remains uncorroded after five years of immersion in seawater, whereas steel corrodes and deteriorates under the same conditions. Titanium alloy hulls for ships are impervious to seawater corrosion. 'Titanium submarines,' constructed from titanium alloys, can dive to depths of 4500 meters, while ordinary steel submarines are easily crushed by water pressure at depths exceeding 300 meters. 'Titanium aircraft' are strong and lightweight; a large titanium passenger plane can carry over 100 more passengers than a similarly weighted conventional aircraft, and can reach speeds exceeding 3000 kilometers per hour, compared to 2400 kilometers per hour for aluminum alloy aircraft. Titanium and zirconium's strong absorption of air can be utilized to create a vacuum. Vacuum pumps made from titanium-zirconium alloys can evacuate air to a level of one part in a billion. In the aerospace industry, titanium can be used to create spacecraft 'outer shells' to protect against high temperatures. The alloy of titanium and nickel is known as 'shape memory alloy.' This alloy, formed into a predetermined shape and then set, will revert to its original form upon slight heating after deformation by external forces. This alloy is currently used in many fields. Titanium carbide (TiC) resembles iron carbide, possessing a metallic luster. However, it has a higher melting point and hardness than iron carbide, making it practically valuable. Food stored in titanium containers retains its color, aroma, and flavor for extended periods. Titanium cookware is lightweight and rust-proof, making it scientifically hygienic. High-pressure containers made of titanium alloys can withstand pressures of 2500 atmospheres. Titanium's applications in surgical procedures are also fascinating. Currently, stainless steel is used for bone grafts, but it has the drawback of requiring removal after bone healing, a painful process. Otherwise, the stainless steel may rust and harm the body. Replacing it with titanium 'artificial bones' would revolutionize orthopedic surgery. In areas of skull damage, titanium plates and screws are used; after a few months, bone will regrow into the small holes in the plates and screws, and new muscle fibers will encapsulate the titanium sheets. The titanium bone structure integrates with the flesh like real bone, providing support and reinforcement. Therefore, titanium is praised as a 'biocompatible metal.' It is now used in knee, shoulder, rib, skull, heart valve, and bone fixation clips. In the steel industry, small amounts of titanium serve as an excellent deoxidizer, denitrogenizer, and desulfurizer. Barium titanate crystals are widely used in ultrasonic instruments and underwater detectors because they generate an electric current when their shape changes under pressure; conversely, applying an electric current changes their shape. When placed in an ultrasonic field, barium titanate generates a current, the magnitude of which indicates the strength of the ultrasound. Conversely, passing a high-frequency current through it generates ultrasound. In gold-plated decorative crafts and daily necessities, the low hardness, susceptibility to punctures, and wear of gold limit its durability. Coating these materials with a layer of titanium nitride results in an appearance almost identical to gold plating, but with greater wear resistance than gold or hard alloys. This coating is praised for its 'imperishable' nature. Organotitanium polymers can be used as surfactants, dispersants, water repellents, or rust inhibitors. Among the four series of hydrogen storage metals currently used by humans, titanium-based alloys are one type and relatively inexpensive. However, a more ideal 'hydrogen storage metal' has not yet been found. Once this problem is solved, hydrogen can be used as fuel.

Give a brief overview of the global distribution of titanium resources.

With the growing market for titanium, what is the global distribution of titanium resources? By the end of 1995, the world's ilmenite (including rutile) reserves and resource base were 33.3 million tons and 164.4 million tons respectively, with a total resource of approximately 230 million tons (TiO2 content, the same below), mainly concentrated in South Africa, India, Sri Lanka, and Australia. The world's titanium iron ore (TiO2) reserves and resource base were 274.3 million tons and 435.3 million tons respectively, with a total resource of approximately 1 billion tons; mainly concentrated in South Africa, Norway, Australia, Canada, and India. By the end of 1996, China's proven reserves of native titanium (magnetic) iron ore (in terms of TiO2) were 357.0409 million tons (including 231.915 million tons of A+B+C grade); ilmenite (sand) mineral reserves were 38.0319 million tons (including 21.4717 million tons of A+B+C grade); rutile mineral reserves were 2.5686 million tons (including 0.7373 million tons of A+B+C grade); and rutile TiO2 reserves were 7.5086 million tons (including 2.4243 million tons of A+B+C grade). If China's A+B+C grade ilmenite sand reserves of 21.4717 million tons in 1996 are converted based on a TiO2 content of 48%, the TiO2 reserves would be 10.3064 million tons, accounting for only 3.83% of the world's titanium iron ore (TiO2) reserves of 270 million tons in the same year; if this is added to the approximately 50% currently usable granular titanium iron ore output (TiO2) reserves of 115.9575 million tons from the A+B+C grade reserves (231.915 million tons) of native titanium magnetite rock ore (TiO2), the total TiO2 reserves would be 126.264 million tons, accounting for 47.76% of the world's titanium iron ore (TiO2) reserves of 270 million tons in the same year. In this sense, China can be called a country rich in titanium iron ore resources. If China's A+B+C grade rutile mineral reserves of 0.7373 million tons in 1996 are converted based on a TiO2 content of 94% into TiO2 reserves of 0.6931 million tons, and added to the A+B+C grade rutile (TiO2) reserves of 2.4243 million tons in the same year, the total would be 3.1174 million tons, accounting for 9.36% of the world's rutile (TiO2) reserves of 33.3 million tons in the same year. This shows that China's rutile resources are not abundant.
