在0.5,1,2和3千巴1)以及800℃,850℃和900℃温度下分别测定了F、B2O3和P2O5对人造花岗岩液体(36wt%SiO2,39wt%NaAlSi3O8,25wt%KAlSi3O8)中水溶解度的影响。水的溶解度随熔体中F和B含量的增大而增大。水溶解度的增加在高压下要比在低压下更明显。在2千巴和800℃下,水的溶解应随着熔体中F含量由0增加到4.55wt%而相应由5.94wt%增加到8.22wt%,相当于线性增长,即0.53molH2O/molF。在2千巴和800℃条件下,当加入4.35wt%B2O3时水的溶解度则增加到0.86wt%H2O,相当于一线性增长.即1.05molH2O/molB2O3。根据测定结果可以确定F和B各自对人造花岗岩熔体中水溶解度的影响(0.5~3千巴)。虽然P对人造花岗岩体系中的相关系有着巨大的影响,但在天然熔体成分中其对水溶解度的影响可以忽略不计。水的溶解度伴随F含量增加而增大的现象是不能根据现有的光谱资料作出解释的(存在水化氯化铝配合物与否)。相反,已证实在含硼含水溶体中有水化硼酸盐(更可能是硼基配合物)存在。
The effects of F, B2O3 and P2O5 on the fluidity of artificial granite (36wt% SiO2, 39wt% NaAlSi3O8, 25wt% KAlSi3O8) were measured at 0.5, 1, 2 and 3kPa1) and 800 ℃, 850 ℃ and 900 ℃ respectively. Effect of water solubility. Water solubility increases with increasing F and B contents in the melt. The increase in water solubility is more pronounced at higher pressures than at lower pressures. At 2 kPa and 800 ° C, the dissolution of water should increase from 0 to 4.55 wt% with a corresponding increase from 5.94 wt% to 8.22 wt%, corresponding to a linear increase, ie 0, as the F content in the melt increases from 0 to 4.55 wt%. 53molH2O / molF. At 2 kbar and 800 ° C, the water solubility increases to 0.86 wt% H2O when 4.35 wt% B2O3 is added, corresponding to a linear increase. Ie 1.05 mol H2O / mol B2O3. Based on the measurement results, it is possible to determine the influence of F and B on the water solubility in the artificial granite melt (0.5 to 3 kPa). Although P has a dramatic effect on the relationships in man-made granite systems, its effect on water solubility in natural melt components is negligible. The increase in water solubility with increasing F content can not be explained by the available spectroscopic data (hydrated aluminum chloride complexes present or not). In contrast, the presence of hydrated borate (more likely a boron-based complex) in the boron-containing aqueous solution has been demonstrated.
