99% alumina ceramic spare plate is a highly durable, wear-resistant component made from aluminum oxide (Al₂O₃) that is 99% pure. It is used as a critical wear part within industrial valves.
99% Alumina: This indicates a very high purity level. The remaining 1-2% consists of other oxide additives (like SiO₂, MgO, CaO) that aid in the sintering process during manufacturing. This high purity results in superior mechanical properties compared to lower-grade alumina (e.g., 92% or 96%).
Spare Plate: This part is specifically designed as a replacement component for valves that handle highly abrasive or corrosive media. It often serves as the seat or a guiding component that bears the brunt of the wear.
