Custom BN Ceramic Crucible Fixture Jig

Q1: What atmosphere is suitable for BN crucible fixture?

A: Best working under vacuum, nitrogen or argon inert atmosphere. Long term service in air should not exceed 900℃, BN will be oxidized at high temperature in air, shorten service life.

Q2: Can you customize shape & dimension? What information do I need to provide?

A: Yes, fully custom available. Please provide engineering drawing (PDF/DXF/STEP), or outer inner diameter, height, hole size, tolerance, working temperature and working atmosphere.
