99% Alumina Ceramic Sagger (Firing Tray)
99% alumina ceramic saggers are high-purity refractory containers designed for high-temperature kiln applications, particularly in the firing of advanced ceramics, electronic components, and precision materials. Made from 99% aluminum oxide (Al₂O₃), these saggers offer exceptional thermal and chemical stability, ensuring minimal contamination and long service life in demanding environments.
**Key Features:**
- **Ultra-High Purity** – 99% alumina content prevents reaction with sensitive materials, ensuring clean firing.
- **Extreme Temperature Resistance** – Withstands continuous use up to **1650°C (3002°F)** in oxidizing or inert atmospheres.
- **Superior Thermal Shock Resistance** – Low thermal expansion reduces cracking during rapid heating/cooling cycles.
- **Excellent Mechanical Strength** – High hardness (Mohs 9) and wear resistance for extended durability.
- **Chemical Inertness** – Resists corrosion from fluxes, glazes, and molten salts.
- **Sintering of advanced ceramics** (zirconia, alumina, silicon nitride)
- **Firing of electronic components** (MLCCs, ferrites, piezoelectrics)
- **High-temperature catalyst supports**
- **Powder metallurgy & precision casting**
- **Laboratory & research kiln use**
