1, High hardness and dense particles. Single-particle roundness is good.
2, The color is pure white, with no impurities, to ensure the wear-resistant layer or wear-resistant paper color and transparency.
3, Uniform distribution of particle size, single-particle shape consistent, with a small amount of wear-resistant effect.
4, Chemical stability and acid, alkali no action, high-temperature stability is very good.
