NSiC Furnace Lining/ Liner

NSiC (Nitride-Bonded Silicon Carbide) lining is a high-performance refractory solution designed for high-temperature furnaces and kilns.

It serves as a protective inner lining that separates the heating elements from the working atmosphere, ensuring stable thermal environments and long service life under harsh operating conditions.

Key Features:
Excellent thermal shock resistance, minimizing cracking during rapid temperature changes.
High thermal conductivity, promoting even heat distribution.
Superior resistance to oxidation and chemical corrosion.
Strong mechanical strength and wear resistance at high temperatures.
Extended service life and reduced maintenance downtime.

Typical Applications:
Muffle linings in high-temperature sintering furnaces.
Atmosphere separation chambers in metal heat treatment and ceramic processing.
Protective lining for continuous and batch furnaces in powder metallurgy, magnetic materials, and electronic components manufacturing.
