4000# Green Silicon Carbide Powder for Optical Glass Grinding Green Emery Powder

Our 4000# Green Silicon Carbide Powder, also known as Green Emery Powder, is a high-performance abrasive specifically engineered for optical glass grinding applications. With its ultra-fine 4000 mesh particle size and exceptional hardness, this product stands out as an ideal choice for precision grinding, polishing, and finishing of various optical glass components, delivering superior surface quality and processing efficiency.
Made from high-purity green silicon carbide (SiC) raw materials through advanced crushing, grading, and purification processes, our green emery powder features uniform particle size distribution, no impurities, and strong wear resistance. The 4000# specification ensures that the powder is fine enough to achieve a smooth, scratch-free surface on optical glass, while maintaining sufficient cutting force to reduce processing time and improve production efficiency.
Unlike ordinary abrasives, our green silicon carbide powder has excellent thermal conductivity and chemical stability, which can effectively dissipate heat generated during the grinding process, avoid thermal damage to optical glass, and ensure the optical performance of the processed products. It is non-toxic, odorless, and environmentally friendly, complying with international environmental standards and suitable for long-term use in industrial production.
This product is widely used in the grinding and polishing of optical glass, such as lenses, prisms, optical fibers, and glass substrates. It is also applicable to other precision grinding scenarios that require ultra-fine abrasives, including semiconductor materials, ceramic products, and precision metal parts. Whether for large-scale industrial production or small-batch precision processing, our 4000# Green Silicon Carbide Powder can meet your high-standard processing needs.
We adhere to strict quality control standards throughout the production process, from raw material selection to product delivery, to ensure that each batch of products meets the specified technical indicators. With competitive pricing, stable supply, and professional after-sales service, we are committed to providing you with high-quality abrasive solutions for optical glass grinding. Choose our 4000# Green Silicon Carbide Powder, and elevate your processing quality to a new level.

The applications of Black silicon carbide powder?

Black silicon carbide powder is produced by smelting quartz sand and petroleum coke inside high‑temperature resistance furnaces. Featuring Mohs hardness of 9.2, good thermal conductivity, moderate electrical conductivity, excellent wear resistance and great chemical stability against acids and alkalis, this cost‑effective SiC material serves numerous industrial sectors across abrasive processing, thermal management, refractory metallurgy and advanced composite manufacturing.
Its most traditional and largest‑volume application lies in the abrasive and surface‑treatment industry. Graded black silicon carbide grits and micro‑powders are widely made into grinding wheels, abrasive belts, sandpapers and polishing pastes. It performs outstandingly for grinding cast iron, non‑ferrous metals such as aluminum, copper and brass, stone, marble, glass and low‑tensile‑strength non‑metallic workpieces. In sandblasting and water‑jet cutting operations, sharp‑edged black SiC particles efficiently remove rust, oxide scale, burrs and old coatings, achieving uniform matte surface finishing for machinery parts, casting components and hardware workpieces.
