Specification of Refractory Raw Material: Black Silicon Carbide Powder Silicon Carbide

Black silicon carbide powder is a key refractory raw material. It is made from quartz sand and petroleum coke. This happens in a high-temperature electric furnace. The result is a very hard and durable substance. It has excellent thermal conductivity. It also resists chemical reactions well. These properties make it perfect for tough industrial jobs.

The powder comes in different grain sizes. You can get coarse grains. You can get fine grains too. The choice depends on your needs. The purity is very important. Good black silicon carbide has high silicon carbide content. It should be over 98%. The carbon content is low. Free carbon should be less than 0.2%. Iron content is also minimal. This keeps its performance strong.

Its hardness is nearly as high as diamond. This makes it great for abrasives. It cuts and grinds materials effectively. It handles high heat without breaking down. So it’s used in kiln furniture. It’s used in furnace linings. It serves well in foundry applications. It withstands thermal shock. It keeps its shape under stress. These features are vital for refractory products.

Density is another key specification. Black silicon carbide is dense. Its specific gravity is high. This contributes to its durability. The powder is chemically stable. It doesn’t react easily with acids or alkalis. This adds to its usefulness. It performs reliably in harsh environments.

Applications of Refractory Raw Material: Black Silicon Carbide Powder Silicon Carbide

Black silicon carbide powder is an important industrial material. It is very hard and durable. Many industries use this material because it has special properties. This powder works well for abrasive applications. Manufacturers put it into grinding wheels, sandpaper, and blasting media. It helps cut, shape, and finish hard materials like metal, stone, glass, and ceramics. The sharp grains make grinding efficient. This material is also vital for refractory products. Refractories handle high heat. Foundries and steel plants use refractories to line furnaces and ladles. Adding black silicon carbide makes these linings last longer under intense heat and wear. Metallurgy benefits from this powder too. It acts as a deoxidizer in steelmaking. This helps remove unwanted oxygen. It can also improve the quality of cast iron. Foundries add it to molten iron to make the graphite structure better. This results in stronger iron castings. Ceramics production uses black silicon carbide. It is mixed into clay bodies. This makes kiln furniture stronger. Kiln furniture holds ceramics during firing. The powder helps these parts withstand repeated heating and cooling cycles. Other industries find uses for it. It serves as a cutting material in wire saws. It is part of certain composite materials. It is used in some electronics applications. Black silicon carbide powder is versatile. Its hardness and thermal properties make it valuable across different fields. It improves performance in demanding industrial settings.
