AC9815 Alumina Crucible, Al2O3 Crucible Cylindrical, 95%, 15 mL

Alumina Crucible, Al2O3 Crucible Cylindrical, 95%, 15 mL Description

Alumina Crucible, Al2O3 Crucible Cylindrical, 95%, 15 mL consists of high-purity alumina (Al2O3) with a 15 mL volume. The material exhibits a density between 3.7-3.9 g/cm³, accompanied by tensile and compressive strengths of approximately ~32 Kpsi and ~300 Kpsi, respectively. The thermal conductivity of 25 W/(m·K) and an operating limit of ≤1500 ℃ enable it to withstand elevated temperatures. A high volume resistivity (>10^14 Ohm·cm) aids in minimising electrical leakage during processing.
