Silicon Carbide: Understanding Grit Sizes for Superior Performance
Silicon carbide, renowned for its high hardness, low expansion coefficient, brittleness, and excellent thermal conductivity, is a remarkable non - metallic mineral product. It is formed at high temperatures above 1800 degrees Celsius using quartz sand (SiO_2), petroleum coke (C), and sodium chloride (NaCl) as basic raw materials, with black and green silicon carbide being the two main types.
When it comes to silicon carbide abrasive production, grit size is a crucial factor. Different industries and applications demand specific grit sizes to achieve optimal results. There are several international standards for defining these sizes, such as the Chinese standards, European standards (FEPA), and Japanese standards (JIS).
For example, under the European standard (FEPA), common product models include F6#, F8#, F10#, F12#, etc. Each model corresponds to a specific basic particle size range. For instance, F16# has a basic particle size range of 1400 - 1180 microns, while F120# is 125 - 106 microns. In the Japanese standard (JIS), 16# silicon carbide has a particle size related to 1230 microns approximately, and 120# is around 109 microns.
The choice of grit size depends on the intended use. In the semiconductor industry, where precision is key, finer grit sizes are often required for tasks like wafer polishing. In abrasive applications for general metalworking, a coarser grit size might be more suitable to remove material quickly.
