'''偏矽酸鈣'''，[[化學式]]為CaSiO<sub>3</sub>，用作高溫絕緣及防火。偏矽酸鈣沒有已知對健康有不利影響。偏矽酸鈣不溶於[[水]]。其矿物为矽灰石（Wollastonite）。

==高溫絕緣==
偏矽酸鈣是常用替代[[石棉]]的一種安全隔熱材料。
==制备==
[[碳酸钙]]与[[二氧化矽]]在高温下反應，化學方程式如下：<br>
:<math>\mathrm{CaCO_3+SiO_2\xrightarrow{\Delta}CaSiO_3+CO_2\uparrow}</math><br>
高爐的熔渣也是偏矽酸鈣，化學方程式如下：<br>
:<math>\mathrm{CaO+SiO_2}\;\xrightarrow\;\mathrm{CaSiO_3}</math>

==用途==
用於陶瓷、塗料、塑膠、橡膠、磨料、電焊、聚合物、染料、冶金、建材、環保及石棉的代用品等。
