Ceramics, unlike most other abrasive grains, are manufactured or artificial abrasives. Although ceramic is more expensive, it can be cheaper to use in the long run because of the longevity of the belt. It is the sharpest and strongest of all the grains and is friable, meaning as it is being used, more new sharp material gets exposed. Ceramic belts are excellent in high heat applications and for coarse grinding and rapid material removal on hard materials like stainless steel. Ceramics are a popular item in the abrasives world for metal fabricators, knifemakers, blade smiths, and more.
