Refractoriness (℃)
1580< Refractoriness< 1770
Feature
Long Time Materials
Material
Silicon Carbide (SiC)
Product Description
1. SiO2: 90-97%
2. High electrical resistivity and impermeability
3. Increased cohesio
4. High compressive and flexural strengths
1. Enhancing the fluid of pouring refractory, reducing the volume of used water, be easy to shape, and raising the production efficiency.
2. Because of its untramicrostructure for gap filling, the compact and intensity of refractory gain rising by a wade margin.
3. TOPKEN Microsilica is a highly effective pozzolanic material, so it's easy to come into being Mullite Phase, under the premise that Al2O3 exists, enhance elevated temperature strength and thermal shock of refractory.
