Our High Purity Conical Alumina Ceramic Crucibles (ARC) are specifically designed for high-temperature applications, offering excellent chemical stability and thermal conductivity. Crafted from top-grade alumina (Al2O3), these conical crucibles are ideal for laboratories, material testing, and various industrial processes. The conical shape ensures efficient material handling and uniform heating, making them perfect for precise experiments and production needs. With superior resistance to corrosion and thermal shock, these crucibles guarantee reliable and durable performance. Suitable for sintering, melting, and analytical procedures, our alumina crucibles are essential for achieving consistent and accurate results. Custom dimensions are available upon request, and covers can be purchased separately.

SKU#	Material	Color	Purity	Maximum temperature
CX-AL-12001	Alumina Ceramic	White	99%	1600 °C

Notes for use:

a, Place the crucible in 105 °C oven for 2h to remove the moisture before the first use

b, Do not heat and cool faster than 5 °C/min <1200 °C or 4 °C/min >1200 °C

C,The bottom of the large crucibles should not be in direct contact with the bottom of the furnace. It is recommended to use alumina footpads or other temperature-resistant materials to raise the crucibles
