Foam-Ceramic-Glass Synthesis Using a Mechanized Extrusive Method of Batch Preparation
The synthesis of inorganic heat-insulating material — foam-glass-ceramic — using activating methods of batch preparation in the form of batch extrusion and autoclaving is examined. Intensification of the interaction of NaOH with the amorphous phases of opal-cristobalite rock occurs, as a result of which the average density of the material decreases significantly. An economic benefit is achieved on account of a proportional reduction of the content of costly sodium hydroxide in the material. The introduction of container-glass cullet into the batch gives an even greater reduction of the average density of the samples as well as NaOH consumption reduction and, therefore, the cost of production of the foam-glass-ceramic.
