Black Silicon Carbide Ultra Fine Powder Description
Black Silicon Carbide Ultra Fine Powder is an inorganic substance with a chemical formula of SiC. It is made by high-temperature smelting of raw materials such as quartz sand, petroleum coke (or coal coke), and wood chips (salt is needed to produce green silicon carbide) through a resistance furnace. Silicon carbide also exists in nature, a rare mineral, moissanite. Among the non-oxide high-tech refractory materials such as C, N, and B, silicon carbide is the most widely used and most economical one.

Black Silicon Carbide Ultra Fine Powder FAQs
Q1: What are the key properties of black silicon carbide ultra-fine powder?
A: Key properties include high hardness, sharp cutting edges, excellent thermal conductivity, chemical inertness, high wear resistance, and very fine particle size distribution.
Q2: How is black silicon carbide ultra-fine powder produced?
A: Black silicon carbide ultra-fine powder is produced by further grinding and milling standard black silicon carbide grit powder to achieve the desired fine particle size. Advanced milling techniques, such as ball milling or jet milling, are often used to achieve ultra-fine sizes.
Q3: How is the quality of black silicon carbide ultra-fine powder verified?
A: Quality is verified using techniques such as particle size analysis (e.g., laser diffraction), chemical composition analysis, and scanning electron microscopy (SEM) for morphological examination. Consistency in particle size distribution and purity is critical for high-performance applications.
