Description
Предмет изобретени Subject invention
1. Сырьева смесь дл муллитосодержащих керамических изделий на основе тугоплавкой глины и минерализатора, отличающа с тем, что, с целью повышени количества муллита в готовом продукте, исключени образовани довитых и агрессивных веществ, она содержит в качестве минерализатора нестабильное при повышенных температурах соединение , например, карбонат, основной карбонат , гидроокись, оксигидрат по крайней мере одного металла из группы: марганец, медь.1. Raw mixture for mullite-containing ceramic products based on refractory clay and mineralizer, characterized in that, in order to increase the amount of mullite in the finished product, to avoid the formation of poisonous and aggressive substances, it contains an unstable compound as an mineralizer, for example, carbonate, basic carbonate, hydroxide, oxyhydrate of at least one metal from the group: manganese, copper.
магнии, железо, при следующем соотношении компонентов, вес. %:magnesium, iron, in the following ratio of components, weight. %:
Тугоплавка глина85-96Refractory clay85-96
Соединение металла в пересчете на его окись4-15. 2. Способ изготовлени изделий из сырьевой смеси по п. 1 путем формовани и обжига , отличающийс тем, что, с целью интенсификации процесса спекани смеси, обжиг в период разложени глинистых минералов - при 800-1100°С - провод т в восстановительной газовой среде при содержании Нг+СО, равном 3-10%, а охлаждение - в окислительной среде.Compound of metal in terms of its oxide4-15. 2. A method of manufacturing articles from a raw mixture according to claim 1 by molding and calcining, characterized in that, in order to intensify the process of sintering the mixture, roasting during the decomposition of clay minerals - at 800-1100 ° C - is carried out in reducing gas at the content of Hg + CO, equal to 3-10%, and cooling - in an oxidizing environment.
