Alumina Ceramic Crucible boats are crafted from high-purity alumina (Al₂O₃), offering exceptional thermal stability, chemical resistance, and mechanical strength. high purity alumina crucibles are capable of withstanding temperatures up to 1800°C, making them suitable for a wide range of high-temperature applications. With their smooth surface finish and precise dimensions, they ensure consistent performance and reliable results in both laboratory and industrial settings.

Property	Unit	Value (99.7% Alumina)
Al2O3 Content	%	≥ 99.7
Bulk Density	g/cm³	≥ 3.90
Max Working Temp	°C	1800
Apparent Porosity	%	< 0.1 (Gas Tight)
Thermal Expansion	10⁻⁶/K	8.0

Our high-density alumina crucibles feature an apparent porosity of less than 0.1%, making them ideal for high-vacuum applications where gas tightness is critical. With an Al2O3 purity of 99.7%, these crucibles minimize impurity leaching during semiconductor sintering or noble metal melting.
