Product Description

Our high-performance silicon nitride ceramic materials are engineered specifically for the aluminum industry, delivering superior thermal and mechanical properties compared to traditional alternatives. This innovation enables groundbreaking products like the L-shaped high thermal conductivity submerged heating appliance, setting a new standard for efficiency and durability in aluminum processing equipment.

Domestically Pioneered: Slip-Cast Silicon Nitride Pouring Spoons & Crucibles

We utilize a pioneering slip-casting formation process to manufacture silicon nitride pouring spoons and crucibles. This method maximizes the inherent advantages of silicon nitride, offering:

Ultimate Thermal Shock Resistance (ΔT 400–500°C)
Superior Non-Stick Aluminum Properties
Excellent Corrosion & Wear Resistance

These products represent the definitive solution for aluminum melt handling, significantly extending service life compared to spoons and crucibles made from other ceramic materials.
