Product Overview:
Silicon carbide sand in nature also exists a rare mineral called moissanite, natural silicon carbide sand due to rare factors, so we need to use the silicon carbide sand is mainly man-made silicon carbide sand, the common way is to mix the quartz sand and coke, the use of silica and petroleum therein, add salt and wood chips, etc., put into an electric furnace, heated to a high temperature of about 2,250 degrees Celsius, we can get the Silicon Carbide, after various chemical processes to get silicon carbide sand. And silicon carbide sand is a kind of granular material made of silicon carbide, also known as golden steel sand or refractory sand.

Silicon carbide sand has the following characteristics:
Chemically stable: silicon carbide sand has good stability in high temperature and chemical corrosive environments, and can resist the erosion of acids, alkalis and oxidants.
High hardness: The Mohs hardness of silicon carbide sand is 9.2-9.5, which is higher than that of general metal and non-metal materials, so it has good usability.
High-temperature stability: Silicon carbide sand can maintain stable physical and chemical properties in high-temperature environments, and is not easy to soften, melt or oxidise.
Good thermal conductivity: Silicon carbide sand has high thermal conductivity and can conduct heat quickly, so it has important application value in high temperature equipment.
Excellent corrosion resistance: Silicon carbide sand has good resistance to corrosive substances such as acid, alkali and oxidising agents, and can be used stably for a long time in harsh environments.
Because of the above characteristics of silicon carbide sand, it has a wide range of applications in the fields of refractory materials, abrasives, electronic device manufacturing and chemical industry. It is widely used in the manufacture of high-temperature furnaces, refractory bricks, furnace linings, abrasives and abrasive materials, as well as in the manufacture of substrates and encapsulation materials in electronic devices. In addition, silicon carbide sand can also be used as chemical reactants, photovoltaic materials and high temperature heat transfer materials.
Application:
1, In the metallurgical field, silicon carbide is mainly used as reducing deoxidiser.
2、In the field of refractory materials and ceramics, the field of silicon carbide micropowder is widely used. Silicon carbide micropowder structural materials represented by ceramic material products have become one of the main products of foreign new material industry market. Only the foreign market needs more than 50,000 tonnes of silicon carbide fine powder annually.
3, in the field of microelectronic products, the new silicon carbide ceramic substrate mainly uses high-purity silicon carbide powder as raw material. Large-scale, very large-scale IC-level substrate material technology requirements have become increasingly high. Therefore, the thermal conductivity of the substrate material appears to be critical.
4, in the field of abrasives abrasives, silicon carbide is used in a variety of grinding tools, such as grinding wheels, emery cloth, sandpaper all kinds of abrasives in machinery,,, automotive, high-speed railway, timber, leather processing and other industries.
5, grinding field with silicon carbide fine micropowder is the photovoltaic industry, semiconductor and piezoelectric crystal industry to produce the main cutting materials for crystal silicon wafers, crystal silicon wafers cutting is the entire solar photovoltaic industry chain is second only to the production of silicon raw materials, and silicon carbide fine micropowder is to build a complete solar energy industry chain in the important link.

Silicon carbide abrasives are harder and sharper than aluminum oxide abrasives, making them more aggressive and faster cutting. However, they are also more brittle, which can lead to faster breakdown and shorter abrasive life.
Support customisation, you can leave your demand on the left side form. We will contact you within 24 hours.
Grit sizes for silicon carbide abrasives range from coarse (24 grit) to ultrafine (1200 grit) and are used for different applications, from rapid material removal to precision polishing.
To choose the right silicon carbide abrasive, consider factors like the material being worked on, the desired finish, the abrasive life, and the equipment being used. Generally, harder materials require finer grits, while softer materials can be worked with coarser grits.
