Garnet sand
Garnet is also called “jade sand” or “natural gold steel”. It has strong hardness and good acid and alkali resistance. It is an aluminum (calcium) silicate with an island structure.
Features
Garnet sand has the characteristics of high hardness, high temperature resistance, stable chemical properties, uniform particles, high grinding efficiency, and no scratches.
Application
Garnet sand is suitable for waterjet cutting industry; all kinds of metal, plastic, wood and other surface sandblasting industries; ultra-fine grinding of machinery industry, precision casting and grinding industry for kinescope glass bulbs, optical glass, silicon wafers, etc.
