March 28,2025
With the rapid development of modern industrial technology, high-purity green silicon carbide micropowder has been widely used in many fields as a new type of high-performance abrasive material. Green silicon carbide micropowder has become a leader in cutting and grinding processing with its unique physical properties and chemical stability. This article will focus on the production process of high-purity green silicon carbide micropowder and its application in various fields.
Ⅰ. Production process of high-purity green silicon carbide micropowder The production of high-purity green silicon carbide micropowder mainly involves raw material selection, synthesis, crushing, grinding, purification and other links. 1. Raw material selection The synthetic raw materials of green silicon carbide are mainly petroleum coke, quartz sand and metallic silicon. In terms of raw material selection, high-quality raw materials need to be selected to ensure the performance of the final product. 2. Synthesis
After the selected raw materials are mixed in a certain proportion, they are heated to a high temperature in a high-temperature electric furnace to undergo a carbon thermal reduction reaction to generate green silicon carbide. This step is a key link in production and directly affects the purity and performance of the product. 3. Crushing and grinding The synthesized green silicon carbide is crushed and ground to obtain particles of a certain size. The purpose of this step is to obtain micropowders of the required particle size. 4. Purification In order to improve the purity of the product, it is necessary to purify the particles after crushing and grinding. This step usually uses physical or chemical methods, such as pickling, water washing, etc., to remove impurities and improve the purity of the product.
