GC2000# green silicon carbide micro powder is a powder material with high thermal conductivity, high refractory temperature, low coefficient of thermal expansion, and high-temperature performance. Its core advantages as a thermally conductive filler for PVC are: good thermal conductivity, high hardness, chemical stability, fine particle size, and good dispersibility, making it ideal for both soft and rigid PVC thermally conductive products.

Black silicon carbide (SiC) is the “work-horse” abrasive grade (α-SiC, > 98 % SiC, low SiO₂/Fe). Because it is the hardest man-made mineral except diamond (Mohs 9.2–9.4, Knoop 2480) and yet costs only a few dollars per kilogram, it is consumed in very large volumes for jobs that simply need cheap, fast cutting and where the dark colour or slight friability is not a problem. The main uses are:

Black SiC F600 polishing powder (particle size about 13–14 μm) is a high-performance fine silicon carbide powder for jade tumbling grinding. It is especially suitable for the finishing and lightening in the jade processing process. It can balance processing efficiency and surface finish, and is widely used in the batch tumbling of various jade materials such as jadeite, nephrite, and agate.

AlN(Aluminum Nitride) ceramic PCB substrate is a high-performance electronic substrate material that uses aluminum nitride ceramic as the core insulating and heat-dissipating base, combined with metal conductive layers (usually copper) to form a printed circuit board (PCB) for high-power, high-frequency electronic devices. Green SiC powder for polishing AlN ceramic surface can acheive a excellent surface toughness.

Carbon residue in green silicon carbide powder negatively impacts grinding performance. Especially when preparing grinding slurry with GC powder 0.5-1um, free carbon affects the viscosity of the silicon carbide grinding slurry, causing abrasive particles to agglomerate, hindering uniform grinding. Therefore, removing free carbon residue from green silicon carbide micro powder is crucial.

Silicon carbide (SiC) powder plays a critical role in enhancing the performance, durability, and functionality of anti-corrosion coatings, primarily by addressing key pain points of traditional coatings (such as poor wear resistance, low hardness, and limited temperature resistance) while reinforcing their core anti-corrosion capabilities.
