изобретение относитс к электротехнической промышленности и может быть использовано дл производства изол торов, а также в различных област х радио- и электронной техники .The invention relates to the electrical industry and can be used for the manufacture of insulators, as well as in various areas of radio and electronic equipment.
Целью изобретени вл етс повышение термостойкости и снижение температуры спекани .The aim of the invention is to increase the heat resistance and lower the sintering temperature.
Шихту готов т следующим образом.The mixture is prepared as follows.
Технический глинозем измельчают в. вибромельнице до размена частиц основной массы 1-3 мкм. Затем измельченный глинозем смешивают с остальными компонентами (тальк предварительно обжигают при 1150 С) в вибромельнице сухим способом. Из полученной массы после увлажнени приготавливают крупку, которую обжигают при 1150 С и затем подверга1834872Technical alumina is ground in. Vibromill before particle exchange of the main mass of 1-3 microns. Then the crushed alumina is mixed with the other components (talc is previously calcined at 1150 C) in a vibrating mill using a dry method. From the obtained mass, after moistening, prepare a grit, which is calcined at 1150 ° C and then subjected to 1834872
