High-Purity Alumina Crucible (99%) – Ø175 × 170 mm

This alumina crucible (OD 175 mm, ID 155 mm, height 170 mm) is made from 99% high-purity Al₂O₃ with a density of 3.9 g/cm³.

Manufactured by isostatic pressing instead of traditional slip casting, the crucible features uniform density, reduced cracking risk, and extended service life.

The isostatic forming process minimizes contamination and helps maintain the raw material purity through sintering. It also ensures better dimensional accuracy and less deformation after firing, making it ideal for use in muffle and induction furnaces.
