Product Description
When working in high-temperature environments, buyers usually focus on three things: temperature resistance, material purity, and service life. The 99% high purity alumina crucible is designed to meet these requirements. Made from high-grade Al2O3 powder and sintered at high temperatures, this ceramic crucible maintains structural stability and minimizes contamination during processing.
Compared with ordinary ceramic crucibles, high-purity alumina crucibles perform better in laboratory analysis, powder calcination, metal melting, and sintering of advanced materials. The dense structure reduces impurity release and ensures consistent experimental results, making it suitable for both research laboratories and industrial production lines.
Product Features
The 99% alumina crucible offers excellent resistance to temperatures up to 1700°C, allowing stable performance in high-temperature furnaces. The high-density structure improves mechanical strength and reduces cracking during rapid heating or cooling. Its chemical stability provides strong resistance to acids and alkalis, making it suitable for aggressive environments. The smooth inner surface prevents material adhesion and simplifies cleaning between uses.
Product Advantages
Longer service life reduces replacement frequency and maintenance costs. High-purity alumina minimizes contamination and protects sample integrity. Excellent thermal shock resistance lowers breakage risk during heating cycles. Multiple sizes and shapes allow flexible selection for laboratory and industrial applications. Custom dimensions are available for specific equipment requirements.

Production Process
Production begins with carefully selected high-purity alumina raw materials. Strict control of impurity levels ensures stable performance at high temperatures. The material is then formed using isostatic pressing, which provides uniform density throughout the crucible body and improves structural strength.
After forming, the crucibles are sintered in high-temperature kilns. This process increases density and enhances thermal stability. Precision machining is performed to ensure dimensional accuracy and a smooth surface finish. Each crucible undergoes quality inspection before packaging to guarantee consistency and reliability.
Packaging and Shipping
Each alumina crucible is packed with protective foam. Bulk orders are packed in export cartons or wooden crates to ensure safe delivery. Custom packaging is available for long-distance transportation.
