Diamond packaging and specifications: 25 or 50 kg woven bags, commonly used particle sizes can be divided into: 80-120 mesh diamond, 40-60 mesh diamond, 0.5-1mm diamond, 1-2mm diamond, 2-4mm diamond, 4-8mm diamond, etc. (Can be customized according to customer needs). Using industrial alumina powder as raw material, it is melted at a high temperature of over 2000 degrees Celsius in an electric arc and cooled. It is crushed and shaped, magnetic separated to remove iron, and sieved into various particle sizes. Its white corundum is suitable for manufacturing ceramics, resin bonded grinding tools, as well as grinding, polishing, sandblasting, precision casting (special corundum for precision casting), etc. It can also be used to manufacture advanced refractory materials. The code "WA" is consistent with international and national standards, mostly for export, and there is also a certain amount supplied to domestic users.

The product granularity is produced according to international standards and national standards, and can be processed according to user requirements for granularity. The universal particle size codes are F4~F320, and their chemical composition varies depending on the particle size. The prominent feature is the small crystal size and impact resistance. If processed and crushed by a self grinding machine, the particles are mostly spherical, with a dry and clean surface that is easy to bond with binders.

Diamond sand, also known as silicon carbide, can be divided into natural diamond sand and artificial diamond sand. Silicon carbide includes black silicon carbide and green silicon carbide. Among them, black silicon carbide is mainly made of quartz sand, petroleum coke, and high-quality silica as raw materials, and is smelted at high temperature in a resistance furnace. Its hardness is between that of corundum and diamond, and its mechanical strength is higher than that of corundum. It is brittle and sharp.

Application of Diamond Sand: (1) As an abrasive, it can be used to make grinding tools such as grinding wheels, oilstones, grinding heads, sand tiles, etc. (2) As a metallurgical deoxidizer and high-temperature resistant material. (3) High purity single crystals can be used to manufacture semiconductors and silicon carbide fibers. Main application: Used for wire cutting of 3-12 inch monocrystalline silicon, polycrystalline silicon, potassium arsenide, quartz crystals, etc. Engineering processing materials for solar photovoltaic industry, semiconductor industry, and piezoelectric crystal industry. Abrasive and grinding tools, silicon carbide has four main application areas, namely: functional ceramics, advanced refractory materials, abrasives, and metallurgical raw materials. At present, silicon carbide coarse materials can be supplied in large quantities and cannot be considered high-tech products. The application of nanoscale silicon carbide powders with extremely high technological content cannot form economies of scale in the short term. Mainly used for grinding and polishing of grinding wheels, sandpapers, sand belts, oilstones, grinding blocks, grinding heads, grinding pastes, as well as monocrystalline silicon, polycrystalline silicon, and piezoelectric crystals in the electronics industry for photovoltaic products.
