天然石(shi)(shi)(shi)膏(gao)(gao)(gao)中用(yong)(yong)途最(zui)廣的(de)(de)是(shi)二(er)水石(shi)(shi)(shi)膏(gao)(gao)(gao)，其有(you)(you)效成分為二(er)水硫酸鈣，一般根(gen)據(ju)礦石(shi)(shi)(shi)中二(er)水硫酸鈣含量(liang)對(dui)石(shi)(shi)(shi)膏(gao)(gao)(gao)進行(xing)等級劃分。石(shi)(shi)(shi)膏(gao)(gao)(gao)應用(yong)(yong)領域較(jiao)寬，產品種類也較(jiao)多(duo)，不同(tong)的(de)(de)用(yong)(yong)途對(dui)石(shi)(shi)(shi)膏(gao)(gao)(gao)原(yuan)料(liao)的(de)(de)質(zhi)量(liang)有(you)(you)著不同(tong)的(de)(de)要求(qiu)，高品位石(shi)(shi)(shi)膏(gao)(gao)(gao)多(duo)被(bei)用(yong)(yong)于特種石(shi)(shi)(shi)膏(gao)(gao)(gao)產品的(de)(de)生產原(yuan)料(liao)，如食用(yong)(yong)、醫用(yong)(yong)、藝術品、模型和化工填料(liao)等；二(er)水硫酸鈣含量(liang)低于60%的(de)(de)石(shi)(shi)(shi)膏(gao)(gao)(gao)礦則(ze)很少(shao)得到應用(yong)(yong)；高于60%的(de)(de)石(shi)(shi)(shi)膏(gao)(gao)(gao)礦石(shi)(shi)(shi)，則(ze)根(gen)據(ju)其含量(liang)的(de)(de)不同(tong)，被(bei)用(yong)(yong)于建(jian)(jian)材、建(jian)(jian)筑(zhu)等各個領域。
