Alumina Square Crucible — The Ideal Choice for Laboratories and High-Temperature Industries!

Precision-sintered from high-purity 99% α-alumina (Al₂O₃), offering excellent chemical and thermal stability. Withstands temperatures up to 1700°C+, exceptional thermal shock resistance, and no cracking even under rapid heating/cooling cycles. The square design facilitates stacking, handling, and observation, with smooth inner walls that minimize sample adhesion for accurate and reliable results.

Key Advantages:
– Outstanding corrosion resistance against strong acids, alkalis, and molten metals
– High mechanical strength, wear-resistant, and long service life
– Low thermal expansion coefficient for superior thermal stability
– Non-contaminating properties, ideal for high-purity sample melting and analysis

Widely used in: precious metal refining in laboratories, powder roasting, high-temperature material calcination, single crystal growth, rare earth purification, semiconductor material preparation, and dental porcelain sintering.

Customizable in various sizes (capacities from a few milliliters to several liters) to meet diverse experimental needs. Strict quality control ensures every piece undergoes high-temperature testing for stable performance.
