CYS - high refractory zirconium, stabilized by yttrium oxide, intended for lining of high temperature installations with operating temperature up to 2300 °С.
CA-90 – zirconium, stabilized by calcium oxide, intended for lining of continious EAF with protective atmosphere at operating temperature of 2000 °С.
CCP – zirconium, high dense refractories made of zirconia or baddeleyite with addition of zircon, intended for lining of high temperature units with operating temperature up to 2000 °С.
