Zirconium SiC Brick: Zirconia‑Modified Silicon‑Carbide Refractory for Chemical & Metallurgical Kilns

TY Refractory’s premium Zirconium SiC Brick is compound‑sintered from high‑purity silicon‑carbide base with zirconium‑oxide additives and premium industrial alumina powder. This composite refractory combines SiC’s high thermal conductivity and mechanical hardness with zirconia’s enhanced thermal‑shock and anti‑corrosion performance for severe high‑temperature chemical and metallurgical operating conditions.

This high‑grade brick maintains stable structural integrity up to 1700°C, featuring high compressive strength and outstanding crack‑resistance. Its dense matrix restricts penetration of alkali vapors, molten slags and corrosive media, avoiding product contamination inside sodium hexametaphosphate furnaces. Excellent thermal‑cycling stability lowers spalling risks under frequent temperature swings.

The multi‑purpose Zirconium SiC Brick is widely used for SHMP chemical kilns, blast furnace critical zones, hot‑blast stoves, hot‑metal ladles and torpedo cars. Custom‑shaped bricks can be strictly produced according to customer drawings for special furnace lining layouts.

Backed by over 20‑year refractory manufacturing experience, our factory holds complete ISO triple‑system certifications and 21 proprietary technical patents. Rigorous batch‑wise laboratory testing guarantees consistent quality. Global chemical and steel plants select our Zirconium SiC Brick to extend furnace campaign life and cut recurring maintenance costs.
