Features
[Black silicon carbide abrasive]
Abrasive refined by causing a thermal reaction to silicon carbide raw materials, composed of quartz stone and petroleum coke in an electric resistance furnace. Because it provides a large grinding force, it can be used in a wide range of fields.
[Main applications]
Base treatment Blasting such as deburring Lapping of glass, crystal and ceramics Letter engraving on stone materials Grindstone raw materials Polishing paper raw materials

Features
[Green silicon carbide abrasive]
Abrasive refined by causing a thermal reaction to silicon carbide raw materials, composed of quartz stone, and petroleum coke in an electric resistance furnace. As it is purer than black silicon carbide, it is ideal for difficult grinding processing.
[Main applications]
Cutting and high-precision lapping of glass, crystal and ceramics Grindstone raw materials Polishing paper raw materials
Grain size distribution (coarse grain)
Grain size standard
| Grain size | Test sieve that 100% of particles must pass through Stage 1: | Test sieve that may stop a set amount of particles and the resulting amount Stage 2: | Test sieve that must stop a set minimum amount of particles and the resulting amount Stage 3: | Two test sieves that, when combined, must stop a set minimum amount of particles and the resulting amount Stage 3 + Stage 4: | Test sieve that may allow a maximum of 3% of particles to pass through Stage 5 | ||||
