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 and chloride furnace
In the design of titanium sponge plant , the general use of open type or closed type three-phase arc furnace smelting of titanium slag. The former low thermal efficiency, high energy consumption, poor labor conditions and low yield.
Chloride furnace has several types, vertical furnace, a sieve plate fluidized chlorination furnace, no sieve fluidized chlorination furnace and molten salt chlorinator etc.. aerospace castings
Furnace type selection depends on the grade of raw materials, harmful impurities (Mg, CA), the content of raw materials, energy consumption and metal yield.
Calcium and magnesium chloride containing fewer impurities titanium raw material, selects the fluidizing chlorination furnace. Molten salt chlorination device is an effective device for processing low grade and high content of calcium and magnesium rich titanium sponge material, but there must be effective facilities disposal or recycling of waste salt.
