摘要
采用分子动力学方法对高压氦作用下二氧化硅微孔的各种形成模式进行了建模。结果表明,在石英熔体淬火过程中控制氦气压力,可以在较宽的范围内连续改变玻璃的结构。所得玻璃的密度在2.2 ~ 1.5 g / cm3之间变化,氦和氖的奥斯特瓦尔德溶解度系数大于一个数量级
High-pressure Helium as a Template for the Formation of a Microporous Silica Structure
The modeling of various modes of formation of microporous silica using high-pressure helium was carried out by the methods of molecular dynamics. It is shown that by controlling the helium pressure in the process of quenching the silica melt, the structure of the obtained glasses can be changed continuously and within wide limits. The density of the obtained glasses varies in the range from 2.2 to 1.5 g / cm3 and the Ostwald solubility coefficients for helium and neon are more than an order of magnitude
