ZIRCONIUM (Showa Denko)
At the current Shiojiri office, Showa Denko started the first production in Japan for brown electrofused alumina in 1934, and white electrofused alumina in 1938. 70 years since, we have been using various high purity materials including alumina from our own Yokohama office, to develop and manufacture a variety of electrofused refractories, applying sophisticated fusion technology and pulverization/granulation technology gained from the manufacture of abrasive material.
