Sandwich Series Products
® Features
The composite sandwich product made of silicon carbide substrate and oxide panel features as high-temperature strength of SiC and low-pollution of oxide. It is applicable to high temperature up to 1450oC or high-load multi-layer and quick-sintering conditions, and can be used effectively to substitute for Mullite to successfully reduce the cost and increase the yield on firing.
® Application
- For electronic and artistic ceramics as manganese, zinc soft magnetic materials.
- For direct or indirect firing of magnetic materials.
- For quick firing or high-density firing under 1450oC.
- For protective gas firing conditions.
