The introduction of diamond grinding wheel used in sapphire processing
1. Sapphire Processing Process 1.1 Sapphire Substrate Wafer Process From the sapphire ingot to the final substrate sapphire wafer, it mainly includes the following steps: crystal growth → crystal pulling → head and tail truncation → rolling grinding → crystal rod orientation → slicing → chamfering and edge grinding → rough and fine grinding → […]
Introduction of diamond grinding wheel for photovoltaic industry processing
Monocrystalline and polycrystalline silicon Silicon is a hard and brittle material with a Mohs hardness of 6.5 and can be made into polycrystalline silicon and single crystal silicon according to the application. Monocrystalline silicon is a relatively active non-metallic element. This crystal has a basically complete lattice structure and is a good semiconductor material with […]
