ng style="font-weight: bold;"> 鉀長石:長石是鉀、鈉、鈣等堿金屬或堿土金屬的鋁矽酸鹽礦物,也叫長石族礦物。ng>
ng style="font-weight: bold;">一、物理性質:ng>
ng style="font-weight: bold;">鉀長石通常也稱正長石,屬單斜晶系,比重2.56~2.59g/cm3.它具有熔點低(1150+—200C),熔融間隔時間長,熔融粘度高等特點。鉀長石硬度波動於6-6.5,比重波動於2-2.5,性脆,有較高的抗壓強度,顏色多為肉紅色。ng>
ng style="font-weight: bold;">二、用途:ng>
ng style="font-weight: bold;"> 用於電焊條、化工、玻璃熔劑、陶瓷坯體配料、陶瓷釉料、搪瓷原料、磨料、磨具、玻璃纖維等其它行業。脫水鉀長石由於含水量遠低於普通鉀長石,產生瞭很多性能,被廣泛應用在很多領域。ng>
