硅灰石 Wollastonite
硅灰石化學式CaSiO3,是一種稀有礦物資源,是獨特的纖維狀結(jié)果的無機粉體材料,具有良好的物理和化學性質(zhì)。硅灰石有很高的白度,有極高的耐熱性和介電性,有很低的吸水率和吸油率,有較好的耐堿性和良好的助熔性,有低生物耐受性、無毒無嗅等特點,是一種理想的白色補強功能性材料。
Wollastonite (CaSiO3) is a rare mineral resource of unique acicular structure with goodphysical and chemical properties. The main features of wollastonite are high brightness, high heat resistance and dielectric properties, low moisture and oil absorption rate good alkali resistance, non-hazardous and so on. It’s very good reinforcement filler.
