白化閃玉與蛇紋石實驗之化學成份變化

Chemical Compositions of Whitened Serpentine and Tremolite

摘要


本研究以臺灣花蓮豐田地區的閃玉與萬榮地區的蛇紋石為固體材料,硫酸溶液為液體材料,進行仿古的白化玉石的熱液實驗,探討閃玉與蛇紋石經硫酸溶液白化後的化學成分變化的影響。研究結果顯示溫度越高,閃玉和蛇紋石之重量損失及主要成分溶蝕越多。

並列摘要


The research uses nephrite from Fengtien and serpentine from Wanrong of Hualian County as soil materials, and sulfuric acid to conduct a hydrothermal experiment simulating the chemical process involved in whitened serpentine and tremolite. The purpose is to examine the chemical reactions that occur when these materials are exposed to sulfuric acid. The results show that the higher the temperature, the more ions of Si, Ma and Ca the nephrite and serpentine lose through hydrothermal alteration.
