解決方案
天然二水(shui)石膏(gao)(gao)(gao)（CaSO4·2H2O）又(you)稱(cheng)為生石膏(gao)(gao)(gao)，經過煅燒(shao)、磨細(xi)可(ke)(ke)得(de)β型(xing)(xing)半水(shui)石膏(gao)(gao)(gao)（CaSO4·1/2H2O），即建(jian)筑石膏(gao)(gao)(gao)，又(you)稱(cheng)熟石膏(gao)(gao)(gao)、灰(hui)泥。若煅燒(shao)溫度為190 °C可(ke)(ke)得(de)模(mo)型(xing)(xing)石膏(gao)(gao)(gao)，其細(xi)度和(he)白(bai)度均比建(jian)筑石膏(gao)(gao)(gao)高。若將生石膏(gao)(gao)(gao)在400-500 °C或高于800 °C下煅燒(shao)，即得(de)地板(ban)石膏(gao)(gao)(gao)，其凝結(jie)、硬化較慢，但硬化后強度、耐磨性和(he)耐水(shui)性均較普通建(jian)筑石膏(gao)(gao)(gao)為好。通常(chang)為白(bai)色(se)(se)、無色(se)(se)，無色(se)(se)透明(ming)晶體(ti)稱(cheng)為透石膏(gao)(gao)(gao)，有時因(yin)含雜質而成(cheng)灰(hui)、淺黃、淺褐等色(se)(se)。
