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.

Although titanium sponge material in the Second
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.
