With the diamond agglomerated grinding fluid and the alumina polishing fluid developed by Zhongji Micro Material, it is possible to achieve the optimal polishing rate and the surface effect treatment for sapphire substrate sheet, sapphire diaphragm, sapphire optical chip, LED sapphire substrate, sapphire optical lens, optical glass, quartz, and other devices...

Sapphire is widely used for precision instruments, window and mirror of laser, semiconductor epitaxial substrate material, and insulated integrated chips, etc. The performance and quality of the above devices depend largely on the precision processing quality of the crystal surface. As the key consumables for precision and ultra-precision processing procedures, the agglomerated diamond grinding materials developed by Zhongji Micro Material play a crucial role in the grinding process of sapphire crystal.

The production by traditional explosion process will result in high cost, limited production capacity, and damage to the natural environment.

Ball-like diamond agglomerated grinding material: Due to its characteristic of spherical multi-edge angle, it can maintain the high grinding force without scratch during the process of grinding and polishing. It is widely used for grinding of the hard and brittle materials such as sapphire, silicon carbide, and gallium nitride.

It has the ball-like shape feature, presenting multi-edge structure in microscope view, and showing slight luster of natural mineral; it has higher cutting capability, and guarantees high precision polishing effect; it has narrow distribution range of particle size, so as to achieve uniform surface roughness; it has stable quality of products, and small difference between batches; it can achieve ultra-high purity.

It is suitable for processing of sapphire, such as grinding of LED chip, diaphragm, watch lens, mobile phone fingerprint identification sheet, and mobile phone camera lens, and other sapphire materials; processing of metal materials, such as stainless steel, die steel, titanium alloy, and other metal materials.

Polishing of sapphire optical chip, LED sapphire substrate, watch lens, crystal, gem optical lens, optical glass, quartz, and germanium wafer of optical fiber and of photovoltaic enterprise; polishing of gallium arsenide; polishing of indium phosphide; polishing of zinc selenide; polishing of optical fiber connector; polishing of optical fiber patch cord; polishing of glass;
