Metallurgical Grade Refractory 80~98%Min 8#~220# Carborundum Sic Silicon Carbide Powder/Lump

Metallurgical Grade Refractory Silicon Carbide (SiC), commonly known as ​​Carborundum​​, is available in both powder and lump forms with purity levels ranging from ​​80% to 98% minimum​​ and mesh sizes from ​​8# to 220#​​. This versatile material is widely used in high-temperature applications such as ​​refractory linings, kiln furniture, and metallurgical processes​​. The wide purity range allows it to be tailored for different industrial needs, balancing performance and cost.

Higher purity grades (up to 98%) are suitable for precision refractories and abrasives, while lower grades (80%–90%) are cost-effective for general refractory and metallurgical uses. The mesh size range (8# to 220#) enables selection of coarse to fine particles, making it suitable for diverse applications—from heavy-duty grinding and abrasion to fine refractory casting and insulation. In its ​​lump form​​, SiC is used to produce ​​refractory bricks, furnace liners, and kiln shelves​​, which require high thermal conductivity and resistance to thermal shock. The ​​powder form​​ is ideal for producing ​​abrasive tools, bonded abrasives, and as an additive in refractory mixes​​ to enhance strength and durability.

SiC's hardness, only surpassed by diamond, makes it highly effective in wear-resistant applications. Its chemical inertness ensures compatibility with molten metals and slags, reducing contamination. Whether used in steelmaking, foundries, or ceramic industries, Metallurgical Grade Refractory SiC in powder or lump form delivers exceptional performance, durability, and thermal stability, making it a vital material for high-temperature industrial processes.
