6 . the density , chemical durability in water , and stability against crystallization of glasses in the na2o - teo2 system are explored and the fragility of glass forming liquid is studied
研究了nazo一teo :系統(tǒng)中不同成分對玻璃密度，化學穩(wěn)定性，玻璃的抗析晶能力，以及玻璃形成液體的脆性等性能的影響。
Na2o - 8teo2 crystal is stable at temperatures below 330 and will decomposed into two crystalline phase including na2o4teo2 and teo2 at 340 or a higher temperature . the phase diagram of sodium tellurite is modified according to the results obtained . the transformation of na2o - 8teo2 into na2o4teo2 and teo2 includes two steps : na2o - 8teo2 is first transformed into an intermediate amorphous phase and then the intermediate amorphous phase crystallizes to form na2o - 4teo2 and teo2 - the intermediate amorphous phase formed during the transformation is amorphous powder
通過對nt _ 8晶相向nt _ 4和teo _ 2晶相的轉變過程的研究發(fā)現(xiàn)，由nt _ 8晶相向nt _ 4和teo _ 2晶相的轉變包括兩個轉變過程，即由nt _ 8晶相向非晶中間相轉變的過程和由非晶中間相向nt _ 4和teo _ 2晶相轉變的過程，在轉變過程中出現(xiàn)的非晶中間相是一種非晶固態(tài)粉末。
This process was propitious to enrich , activate , transport the copper . in different alteration granodiorite porphyry , sio2 , k2o , cu , mo are depleted in the fresh and weakly altered rock , and are enriched in the strongly altered rock , cl is also enriched in the strongly altered rock . but na2o and fe are extracted from the porphyry into the ore - forming fluid , especially the presence of fe is in favor of cu deposition
在銅廠巖體不同的蝕變帶中， sio _ 2 、 k _ 2o 、 cu 、 mo等從新鮮斑巖甚至弱蝕變帶中帶出，而在強蝕變帶強烈富集， cl同樣有在強蝕變巖石中富集的趨勢；而na _ 2o 、 fe從斑巖體中帶出，進入流體相中，流體中大量fe的存在，有利于銅的沉淀、富集成礦。
Results show that both the density and the chemical durability of glasses decrease with the increase of na2o content . on the other hand , the stability against crystallization of glasses increases gradually with the increase of na2o content . glasses containing 20 ~ 25mol % na2o have the strongest stability against crystallization . the glass forming liquid in the na2o - teo2 system is moderate fragile and the fragility of glass forming liquid increases with t
該系統(tǒng)玻璃的抗析晶能力和玻璃形成能力與試樣的成分有很大關系，隨著成分中氧化鈉含量的升高，玻璃的抗析晶能力和玻璃形成能力則逐漸升高，當氧化鈉含量在20一25mol %之間時，玻璃的抗析晶能力和玻璃形成能力最強。
