The principle of production of titanium sponge

Titanium sponge is a basic link of making titanium ingot and titanium indispensable and intermediate products, refined titanium sponge, high cost of titanium sponge ingot,restricted the development of titanium industry, affecting a wide range of application of titanium. I GB sponge titanium by hardness is divided into 6 grades, titanium sponge isloose and porous sponge, high surface area, more lively, easy oxidation. Titanium sponge is not easy to long-term storage. According to regulations, sponge titanium alloy pump grade 0 -5 total of six grades (quality, purity%) is generally 99.1 ~ 99.7, impurity elements (% quality) a total of 0.3 ~ 0.9, impurity elements oxygen (% quality) is 0.06 ~0.30, hardness (HB) of 100 to 200.
