Latest Patents

Haga's latest patents include the development of stabilized electrocast zirconia refractories. These refractories comprise fine block crystals of zirconia, which exhibit a high bulk density due to their dense texture. They also possess a higher bending strength compared to conventional calcined zirconia refractories. The stabilized electrocast zirconia refractories are produced by pouring an electrofused melt of a blend of zirconia-base material and a stabilizing agent into a mold. The solidification process involves cooling the bottom part of the mold forcibly. Additionally, Haga has developed reinforced electrocast zirconia refractories, which demonstrate extremely high bending strength achieved through heat treatment of the stabilized electrocast zirconia refractories under specified conditions.
