水鎂石用途

發表時間:2022-01-13

水鎂石礦床是我國20世紀80年代末新發現和新開發的礦種。它的主要用途如下。

1)作為提煉金屬鎂的優質原料。它含MgO 69%,含金屬鎂41.6%,遠高于目前用來提取金屬鎂的白云巖中的含鎂量(白云巖MgO理論值為21.7%)。

2)制造阻燃劑的原料。

3)制造高級耐火材料,通過把水鎂石提煉成方鎂石(MgO)得到高級耐火材料。

4)作為橡膠、塑料、人造纖維、電絕緣材料的添加原料。

5)作為環境保護材料——除硫劑。

6)作為造紙業的弱堿性反應劑,并代替石灰處理造紙廠的污水。

7)電熔水鎂石還用做電子、核反應堆、核火箭裝備的結構材料。

8)作為紅外線和紫外線設備材料。

9)色澤美觀的水鎂石可作雕刻材料。

10)纖維狀水鎂石的用途與石棉完全一樣,甚至應用范圍更廣。
