Invention relates to artificial fused silicate ceramic materials, particularly cast stone compositions, and is meant for making bulletproof armoured plates (boards) of bulletproof vests. Besides the defence industry, the invention can be used in construction, ore dressing and other industries. The disclosed stone cast material has components in the following ratio, wt %: SiO2 43-45; Al2O3 15-16; CaO 9-17; FeO 5-8; MgO 8-9; Fe2O3 3-5; TiO2 1-1.5; K2O and/or Na2O 2.5-4; Cr2O3 2-2.5 and CaF2 1.5-2. Owing to use of cheap technologies, raw material and optimum content of additives, the stone cast material has a lower cost. Availability of dissipative properties which meet GOST R 50744-95 "Armoured garments. Classification and basic requirements" attests to its suitability for making bulletproof armoured plates of bulletproof vests. |

Method of producing glassceramic material Method relates to production of construction materials, particularly to use of ash from refuse incineration plants for processing solid domestic wastes, followed by recycling thereof in production of highly efficient and environmentally safe construction articles. The method is characterised by that glass mass is obtained from a mixture containing up to 70% ash, 20-40% silica-containing component and up to 20% alkali-containing component. The obtained articles undergo crystallisation in a single step at temperature 900-1100°C and holding for 60-120 minutes or in two steps at temperature 700-850°C and holding for 30-60 minutes and at temperature 900-1100°C for 60-120 minutes. |

Method of manufacturing vermiculite-based glass crystal material Process is accomplished by mixing vermiculite with limestone, reductive melting, separating silicate fraction of melt, and transferring it into X-ray amorphous state by pouring it into water and subsequent one-step heat treatment. In order to reduce heat treatment time, this operation is conducted under self-propagating crystallization conditions consisting in that elevated temperature wave front emerges owing to phase-transfer energy and it propagates at a velocity of 13 mm/min. |
