硅灰石 Wollastonite
硅灰石化学式CaSiO3，是一种稀有矿物资源，是独特的纤维状结果的无机粉体材料，具有良好的物理和化学性质。硅灰石有很高的白度，有极高的耐热性和介电性，有很低的吸水率和吸油率，有较好的耐碱性和良好的助熔性，有低生物耐受性、*无嗅等特点，是一种理想的白色补强功能性材料。
　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.
