Effect of the component composition and oxidation – reduction characteristics of mixes on foaming of pyroplastic silicate pastes

  • O. V. Kaz’mina
Article

The effect of the composition of mix based on different silica raw material and the oxidation-reduction characteristic of the components on the foaming process in obtaining foam-glass-crystalline materials is examined. It is established that foam-forming mixes belonging to the transitional oxidation-reduction group, whose oxidation coefficient lies in the range 25 – 100 are optimal for foaming. The oxidative and reducing mixes are characterized by a low foaming ratio and high degree of nonuniformity, which requires adjusting the composition by changing the ratio of the reducer oxidizer.
