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.

机械分批法制备泡沫-陶瓷-玻璃

通过分批挤压和高压灭菌形式的分批制备活化方法，研究了无机绝热材料泡沫玻璃陶瓷的合成。NaOH与蛋白石-方石英岩石的无定形相之间的相互作用会增强，结果是材料的平均密度显着降低。由于材料中昂贵的氢氧化钠含量成比例减少，因此获得了经济利益。将容器玻璃碎玻璃引入该批料中会进一步降低样品的平均密度，并减少NaOH的消耗，从而降低泡沫玻璃陶瓷的生产成本。
