5 FAQs of Black Sic/silicon 10-100mm And Silicon Carbide Powder Sic For Casting

What is Black Silicon Carbide (SiC) 10-100mm and Silicon Carbide Powder used for in casting?
Black Silicon Carbide (SiC) 10-100mm grains and powder are abrasive, refractory materials used in metal casting for mold and core production. The granular form (10-100mm) strengthens molds, improves heat resistance, and reduces thermal expansion. The powder is blended into coatings or refractory mixes to enhance surface finish, prevent metal penetration, and improve mold durability under high temperatures.

Why choose Silicon Carbide over other refractory materials for casting?
Silicon Carbide offers superior thermal conductivity, high hardness, and exceptional thermal shock resistance. It maintains structural stability at temperatures up to 1600°C, outperforming quartz or clay-based materials. Its low thermal expansion minimizes cracking, while its abrasion resistance extends mold lifespan, reducing replacement costs and downtime in foundries.

What sizes of Black SiC are ideal for different casting applications?
The 10-30mm grains are used for bulk mold reinforcement in large castings like steel ingots. Medium sizes (30-60mm) suit general-purpose molds for iron or aluminum. Larger grains (60-100mm) provide extra thermal buffering in high-mass pours. The powder (micron to sub-millimeter grades) is ideal for creating smooth mold coatings or mixing into refractory linings for precision castings.

How is Silicon Carbide Powder applied in casting processes?
The powder is mixed with binders or solvents to create slurry coatings applied to mold surfaces. This layer prevents molten metal from sticking, reduces gas defects, and improves surface finish. It’s also added to sand molds or ceramic cores to boost refractoriness. For ferrous metals, SiC powder helps control cooling rates, minimizing shrinkage flaws.

Are there safety or storage guidelines for handling SiC products?
Store Black SiC grains and powder in dry, sealed containers to prevent moisture absorption, which can affect performance. Use gloves and masks when handling the powder to avoid inhalation or skin irritation. While chemically inert, avoid mixing with strong acids or alkalis. The material is non-combustible and has no shelf-life limitations if stored properly.
