Refractory Grade 88-90 Silicon Carbide
What Grade 88-90 Silicon Carbide Is
Refractory Grade 88-90 Silicon Carbide is manufactured through an electric-resistance furnace process and refined to achieve a purity level well-suited for refractory formulations. This grade is valued for its ability to endure sharp temperature fluctuations, oxidative environments, and prolonged heat exposure, all while maintaining structural integrity.
Thanks to its inherent hardness, high melting point, and strong thermal conductivity, the material enhances the mechanical stability of refractory bodies. When incorporated into shaped bricks, monolithic refractories, or castable mixtures, the SiC particles reinforce the matrix and reduce the likelihood of cracking or deformation. This makes the product particularly effective in industries that operate continuous or cyclic high-temperature equipment.
The 88–90% SiC content offers an ideal balance between performance and cost, making it suitable for furnace linings, burner blocks, tap-hole components, kiln furniture, and various insulating layers. Its resistance to slag attack and chemical corrosion helps extend the service life of refractory installations in steelmaking, ceramics, non-ferrous metal processing, and energy sectors.
Each batch undergoes grading to ensure accurate particle distribution tailored for refractory manufacturing. The material is also inspected for density, impurity levels, and thermal expansion behavior. Custom sizes-including fine, medium, and coarse fractions-are available to meet different formulation requirements. Packaging is designed to preserve dryness and prevent contamination during transport and storage.
