ПЕРСПЕКТИВНАЯ ОЦЕНКА РЕСУРСОВ АЛЬТЕРНАТИВНЫХ ВИДОВ АЛЮМОСИЛИКАТНОГО ОГНЕУПОРНОГО СЫРЬЯ ДАЛЬНЕВОСТОЧНОГО РЕГИОНА РОССИИ

Abstract

The presence of a refractory industry characterizes the degree of industrialization. countries. Of the more than two hundred countries in the world, there is a developed refractory industry in about 35 countries. In Russia, the extraction and production of natural refractory raw materials is carried out in small quantities, amounting to units of percent of the total required quantity. The main raw material for its production is scarce and expensive alumina imported from China and other countries, 2/3 of which fall on aluminosili-cate refractories. According to the results of regional and thematic works on the territory of the Far Eastern Region of Russia, the scales of development of high-alumina formations of various genetic types have been determined: sedimentary-metamorphic (sillimanite, distene, andalusian), hydrothermal-metasomatic (alunite, alunite-dickite, alunite-diasporic), sedimentary (kaolinite), magmatic (anorthosite, labrador-anorthosite, nepheline and leucite), according to physico-chemical and technological properties (alumina content of 20-40% or more, fire resistance over 1580°C), the results of industrial research satisfying the requirements for refractory raw materials of alternative types. The presented rather extensive factual material on natural types of fire-resistant raw materials in the Far East testifies to the great potential for the formation of a raw material base for the production of refractories, the prospects of which are quite definite for the economy.
