Titanium is a chemical element with the chemical symbol Ti and an atomic number of 22. It is a silver-white transition metal characterized by its light weight, high strength, metallic luster, and good corrosion resistance (including seawater, aqua regia, and chlorine gas).Due to its stable chemical properties, good resistance to high and low temperatures, resistance to strong acids and alkalis, as well as high strength and low density, it is widely used in various fields.
Titanium alloy is an excellent material for making sports goods.For example, golf club heads made of Ti-6Al-4V alloy are popular among sports enthusiasts in the United States, Japan, and Europe. The amount of titanium used for the manufacture of titanium golf clubs is as high as more than 6,000 tons per year.In addition, titanium alloy is widely used in sports goods such as tennis rackets, badminton rackets, ski poles, snow shovels, mountain climbing ice poles, mountain climbing nails, sledges, fencing protective masks, fishing rods, bicycles, etc.
2. Daily necessities
Glasses frame: The advantages of titanium-made glasses frames are corrosion resistance, color stability, and light weight, with a single frame weighing only 10-20g. Therefore, it is very popular among consumers.Currently, there are pure titanium products, Ti-Ni superelastic products, and other titanium alloy products on the market.It is reported that Japan consumes hundreds of tons of titanium for glasses frames every year.
Watch: Watches with titanium cases are already on the market.Currently, dozens of watch factories in the world produce this kind of watch.Among them are all-titanium cases, titanium-tungsten alloy cases, and special titanium watches for athletes and divers.
Other titanium daily necessities: such as cutlery, including knives, spoons, forks, and plates.Accessories such as cameras, handbags, thermos flasks, seals, earrings, bracelets, rings, necklaces, tie pins, brooches, and brassieres.
The highly-focused curved roof of the National Center for the Performing Arts in China is made entirely of titanium metal plates, which is a typical case of the use of titanium in architecture. This dome uses about 100 tons of titanium.According to relevant information, titanium is used in roofs, window frames, eaves, gables, rain-proof wall barriers, fences, exterior decorative panels, interior decorative materials, as well as monuments, epitaphs, brand names, box houses, makeup columns, air conditioners, and other aspects.
4. Titanium dioxide
Titanium dioxide is an oxide of titanium, a snow-white powder, and the whitest thing in the world. One gram of titanium dioxide can coat more than 450 square centimeters of area with snow-white color.It is five times whiter than the commonly used white pigment, lithopone, and is therefore the best pigment for preparing white paint.Titanium dioxide can be added to paper to make it white and opaque, with an effect 10 times greater than other substances. Therefore, titanium dioxide is added to banknote paper and art paper.
The main application areas of titanium dioxide are coatings, plastics, inks, and papermaking. Titanium dioxide is used in the rubber industry as both a coloring agent and a reinforcing, anti-aging, and filling agent.Adding titanium dioxide to white and colored rubber products results in resistance to sunlight, no cracking, no discoloration, high stretchability, and resistance to acid and alkali under sunlight exposure.
Titanium dioxide is also increasingly widely used in cosmetics.Due to its non-toxic nature and superiority over lead white, titanium dioxide is used almost exclusively to replace lead white and zinc white in various powders.Adding only 5%-8% of titanium dioxide to the powder can achieve a permanent white color, making the fragrance smoother, with adhesion, absorption, and hiding power.Titanium dioxide can reduce the feeling of greasy and transparent in gouache and cold cream.Titanium dioxide can also be used in various other fragrances, sunscreen creams, soap flakes, white soaps, and toothpaste.
In addition, due to its non-toxic, tasteless, white powdered form and low content of heavy metals, food-grade titanium dioxide can be used as a food additive.
5. Titanium also has memory function, superconductivity and hydrogen storage function.
For example, titanium-nickel alloy has one-way, two-way and all-round memory effect at a certain ambient temperature, and is recognized as the best memory alloy;niobium-titanium alloy exhibits zero resistance and complete diamagnetism when the temperature is below the critical temperature, making it the best material for energy transmission;titanium-iron alloy has the characteristic of hydrogen absorption, which can store a large amount of hydrogen safely and release it in a certain environment.This has great potential for applications in hydrogen separation, hydrogen purification, hydrogen storage and transportation, manufacturing of heat pumps and batteries powered by hydrogen, etc.
The characteristics and applications of titanium have been increasingly valued by people, and have been applied to varying degrees in daily life. Titanium has become one of the indicators to measure the level of national living standards, and with the improvement of people's living standards, the application prospects of titanium will be more extensive.
