Kiln Furniture & Refractories
SINSIC
Overview
SINSIC (silicon nitride-bonded SiC) features excellent thermal stability and thermal conductivity for heat treatment, and helps stabilize and streamline manufacturing processes. These superior kiln furniture and refractories are compatible with large-size, thin products as well as products with complex shapes. We have prepared a broad lineup of shapes to meet a diverse range of needs.
Characteristics
- Maintains high strength across a wide temperature range
- Resistance thermal shock
- Resistance to wear and corrosion
- High thermal conductivity
- Resistance to chemical reaction
