Crude titanium
tetrachloride is refined
by distillation.
Titanium tetrachloride is reduced
by molten magnesium in a metal
reaction vessel to produce titanium
sponge. Then, magnesium and
magnesium chloride are
separated through evaporation in
a vacuum under high heat.

Products
The current process for producing titanium was developed by
Dr. Kroll in 1946. In 1952, our company became the first
company in Japan to succeed in commercially manufacturing
titanium and we are now among the world’s largest makers
of this product.
Titanium sponge is mainly manufactured in Japan, the
United States, Russia, Kazakhstan, Ukraine and China.
However, only a few manufacturers, including our company,
Titanium Sponge
have the technology for manufacturing high-quality titanium
sponge (referred to as premium grade) for use in the
manufacture of critical parts such as aircraft engine
components.
Due to our capability to develop unique technologies and
our accumulated expertise, we are recognized by our
customers as a leading manufacturer of titanium sponge, in
terms of both quality and quantity.
We also manufacture titanium ingots using titanium
Titanium Ingot
sponge as the primary raw material. Distinctive features of
our titanium ingots include their excellent surface condition
and high internal quality. Lightweight, strong and rustproof,
Production Capacity
our titanium ingots are processed into pipes and sheets;
pipes for such large-scale facilities as large-scale power
plants, petrochemical and seawater desalination plants,
and sheets for heat exchangers used in ships and LNG
manufacturing plants. We intend to further expand our

Our high-purity titanium, with its high purity levels from
4N5 (99.995%) to 5N (99.999%), is mainly used for
producing high-purity titanium sputtering targets used in
the semiconductor industry.
The titanium powder “TILOP” manufactured by the gas
atomization method offers excellent fluidity due to its
spherical shape, and is used as a raw material of
