FAQ Section

Shelf Life and Storage Requirements

Boron nitride ceramic rods have a long shelf life when stored properly. Keep them in a dry, cool place away from direct sunlight and moisture. Avoid exposing the rods to extreme temperature swings during storage to maintain their integrity.

Use in Oxidizing Environments and Temperature Limits

Our hot-pressed BN ceramic bars handle high temperatures well but are best used in non-oxidizing or inert environments above 1400°F (760°C). In oxidizing atmospheres, avoid temperatures above 1200°F (650°C) to prevent surface degradation.

Machining Recommendations and Tooling Advice

Machining machinable boron nitride tubes is straightforward with proper tools. Use sharp carbide or diamond-coated tools for clean cuts and to extend tool life. Avoid excessive heat buildup by using coolant or working at moderate speeds. This keeps your rods precise, minimizing breakage or chipping.
