Amorphous boron is an amorphous elemental boron with no long-range ordered crystalline structure. It appears as a dark brown to black fine powder, and its properties differ significantly from crystalline boron.
Hexagonal boron nitride (h‑BN) powder acts as high‑performance functional filler for thermal conductive coatings. It delivers high in‑plane thermal conductivity to improve heat dissipation capacity of coating layers, while retaining excellent electrical insulation, so the coated surface will not cause short‑circuit risk for electronic devices.
It has superior high‑temperature oxidation resistance. The coating filled with h‑BN keeps stable under long‑term high‑temperature service up to 900 °C in air, without obvious performance degradation. Its layered platelet structure brings good lubricity, lowering coating surface friction coefficient and enhancing scratch‑resistant property of the coating film.
h‑BN features outstanding chemical inertness. It resists acid, alkali and most solvent erosion, improves the corrosion resistance and weather resistance of finished coatings. Unlike carbon‑series thermal conductive fillers, its white tone supports light‑colored coating formulation, avoiding dark‑color limitation. In addition, h‑BN shows low dielectric loss, making it fit for thermal‑conductive coatings used in high‑frequency electronic scenarios.
Silicon carbide fine powder (black/green SiC fine powder, such as 10 micron, 7micron, 5 micron ultrafine powder) can be used as a PTFE-modified wear-resistant filler. It is one of the mainstream hard ceramic fillers for industrial wear-resistant self-lubricating coatings, suitable for water-based/solvent-based PTFE composite coatings and organosilicon-PTFE high-temperature wear-resistant coatings.
Optical fiber preforms are optical fiber communication materials made of high-purity quartz glass. Due to its unique physicochemical properties, Green SiC powder GC1200# offers significant advantages in the polishing process of optical fiber preforms. The following is a detailed analysis of its core advantages:
Green silicon carbide powder possesses exceptionally excellent chemical corrosion resistance and high-temperature chemical inertness. Thus it can effectively improve the durability of filter materials in the petrochemical industry. Green silicon carbide powder 6000mesh (about 2.5μm) is a high-purity, high-fineness ultrafine silicon carbide powder. It obtains benefit for the molding and production of filter ceramic membranes and foamed ceramics.
Black silicon carbide F500 powder is made from fine processing, achieving a purity of up to 98.5%. Its high purity and good flowability make it an excellent ceramic filler in water-based anti-corrosion industrial paints, enhancing the paint’s performance in terms of corrosion resistance, abrasion resistance, and weather resistance.
