Chlorination & Reduction Technology
The major products manufactured by the Toho Titanium Group are titanium sponge andtitanium ingot cast by vacuum melted titanium sponge.

Titanium Metal

Our titanium sponge is produced by applying a combination of our own technology andtitanium tetrachloride is generated by chloride reaction with titanium ore (main ingredientis TiO₂) and, afterward reacted with magnesium to remove chlorine by the so-called Kroll
Process and consequently titanium sponge is produced.
We employ vacuum distillation to eﬀectively remove magnesium and magnesium chloride
entrapped in the titanium sponge after the reduction reaction. This allows us to produce
high-quality titanium sponge that is suitable for melting. Our square-type DC Slab®, EB ingot(produced by EB cold hearth melting) and round-type VAR ingot (produced byconventional double or triple vacuum arc remelting) can be applied to a wide range of
products to accommodate customer needs.
