nepheline n.【礦物】霞石。

nephelinite

Analysis of k and na in nepheline were curried out with higher precision and repeatability by means of adding fluohydric acid during sample melting to remove sio2 , adjusting the ratio of k and na in the solution to reduce the mutual interference of the two elements , and adding cesium chloride to eliminate ionization interference 摘要本方法用于測定霞石中的鉀、鈉,主要通過在溶樣時加入氫氟酸除去二氧化矽,調整溶液中鉀、鈉的含量,消除互相之間的干擾,加入氯化銫消除電離因素的干擾,提高了分析結果的準確性和重現性,使測定結果更接近化學分析值。

The rock texture , mineral occurence feature , ore electronmagnetic milling and applied possibilities in ceramics and glass of the jadeite metamorphic aegirine - augite nepheline syenite in suizhou , hubei were studied . the results show that the ore deposit combines the advantages of mining and milling , and the finished ore by single electronmagnetic milling may be fully utilized as the raw materials for ceramics and glasses . meanwhile , another important fact is that the compositon with 90 percent raw ore may be manufactured into the wall and floor tiles with glaze , which was affirmed by a lot of experiment research 隨州硬玉質變霓霞正長巖的巖石組織結構、礦物賦存狀態、礦石可選性和玻璃陶瓷原料應用試驗研究表明:該資源具有易采易選兩大優點,礦石經單一磁選的精礦可作玻璃和陶瓷的原料;同時已反復試驗證實該資源可燒成原礦用量達90的釉面墻地磚。
