What are the characteristics of titanium sponge and titanium dioxide?
Titanium sponge production is the basic link in the titanium industry and is the raw material for titanium materials, titanium powder and other titanium components. Turn ilmenite into titanium tetrachloride, then put it into a sealed stainless steel tank, fill it with argon, and react with metal magnesium to obtain titanium sponge. This porous titanium sponge cannot be used directly and must be melted into liquid in an electric furnace before it can be cast into titanium ingots.
Uses of titanium sponge:
Sponge titanium is the raw material for refining titanium metal, which can be made into metal materials such as titanium nails. Sponge titanium can be used as a coating material after being ground, and is often used on the surface of some mechanical equipment. Sponge titanium is a kind of spongy titanium metal made by metal reduction method. Its purity is generally between 99.1 and 99.7. According to the purity can be divided into five grades. The production of sponge titanium is a very important link in the titanium industry, and it is also the main raw material for some titanium materials. It took about 120 years from the discovery of titanium to the production of titanium metal. Many researchers continued to explore, and finally produced sponge titanium in 1948.
The scientific name of titanium dioxide is titanium dioxide (TiO2), molecular weight: 79.88. It is a white inorganic pigment, non-toxic, with optimum opacity, optimum whiteness and brightness. It is considered the best white pigment in the world. , Widely used in paint, plastic, paper, printing ink, chemical fiber, rubber, ceramics, cosmetics and food additives and pharmaceutical industries.
titanium dioxide : anatase type, referred to as type A; rutile, referred to as type R. The coatings industry is the largest user of titanium dioxide, especially rutile titanium dioxide, most of which is consumed by the coatings industry. Accounting for more than 50% of titanium dioxide consumption. With the development of my country's automobile industry and construction industry, the coating industry not only has greater demand for titanium dioxide in quantity, but also has higher requirements for variety and quality. Coatings made of titanium dioxide have bright colors, high hiding power, strong tinting power, low dosage, and many varieties. They protect the physical stability of the medium, enhance the mechanical strength and adhesion of the paint film, and prevent cracks. , Prevent the penetration of ultraviolet rays and moisture, and extend the life of the paint film.
