99% Alumina Ceramic Crucible - Premium Corundum Crucibles for High Temp Applications

Core Introduction

Our 99% alumina corundum crucibles represent the pinnacle of high-temperature ceramic ware, engineered for demanding laboratory and industrial applications. Manufactured from premium-grade 99% pure aluminum oxide (Al₂O₃), these crucibles offer exceptional thermal stability, chemical inertness, and mechanical strength. The high-density corundum structure ensures minimal porosity and maximum durability under extreme conditions.

With a maximum service temperature of 1800°C (3272°F) and exceptional thermal shock resistance, these crucibles maintain structural integrity through rapid temperature cycling. The ultra-high purity composition provides superior resistance to chemical attack from acids, bases, and molten metals. Unlike lower-purity alternatives, our 99% alumina crucibles exhibit virtually no contamination risk, making them ideal for analytical chemistry, metallurgy, and materials research where purity is paramount.

These crucibles are specifically designed for:

• High-temperature melting and sintering processes

• XRF sample preparation and fusion

• Precious metal analysis and refining

• Glass and ceramic research

• Semiconductor material processing

• Catalyst research and development

• Educational and R&D laboratory applications

Each crucible undergoes rigorous quality control, including dimensional verification, visual inspection for defects, and batch testing for thermal performance. Our manufacturing process ensures consistent wall thickness, smooth interior surfaces, and precise geometry for optimal heat distribution and sample containment.
