Physical-Chemical Studies of Gaizes as Alternative Raw Materials for the Production of Foam Glass and Foam Materials
- 25 Downloads
Data from physical and chemical studies of gaizes are presented—chemical, phase, and granulometric compositions, degree of crystallinity, and thermal stability in the temperature interval 90 – 1000°C. It is shown that the silica in the studied gaizes exhibits heightened reactivity and the gaizes have low crystallinity and high dispersity, which promotes activation of structural-chemical transformations in gaizes when they are heated.
