Metal thermal reduction method to produce titanium sponge-like. Purity% (by mass) is generally 99.1 to 99.7. % Impurity element (mass) amount of 0.3 to 0.9% oxygen impurity element (mass) of 0.06 to 0.20, hardness (HB) of 100 to 157, depending on the purity to MHTi4 WHTiO into five levels.

Titanium sponge plant extract purity methods
Secondary smelting produce consumable content of impurities TA2 pure milled raw material ingot Table relationship , which is the average of 100 titanium ingots . As can be seen from the table, iron , titanium ingot and the nitrogen concentration of the titanium sponge plant has not changed , the purification effect of sky ; silicon, carbon and oxygen titanium sponge increased slightly , and no purification effect, but in the smelting process is increased impurity contamination volume ; Lee hydrogen chloride purification obvious effect , do not hold the product in a reduced number of chlorine and level . It also shows that the main role of vacuum distillation . Both the total amount of impurities from the point of view , slightly lower titanium sheet metal than the titanium ingot of titanium sponge plant impurities, by lowering the melting sponge drink chlorine , and slightly increases the oxygen and other impurities. In short , a slight increase in the purity of titanium , but it remains in a substantially horizontal magnitude .State Reserve policy affected by early December , some titanium sponge plant titanium sponge enterprises to improve the sales price,so despite favorable policies , but did not titanium alloy plates change the current market downturn titanium sponge plant trend.Some titanium sponge plant enterprises raise product prices , but signs of recovery as the market did not like before . Since downstream firms reflect flat, high offer titanium sponge plant enterprises become castles in the air , and soon dropped back to previous levels. And during the bidding , some companies did not follow the big companies with price increases.
