Description
Вследсти- е возп1п иовеин при быстром нагреве и охлаждении при гор чем прессоваиии внутренних напр жений в прессованных телах, последние иодвергаютс отжигу в муфельной печи с доведением температуры до 1500° и с последующим медленным остыванием в течение 1-2 час. Сопротивление износу и :механическа прочность тел из корунда при этом, значительно увеличиваетс .Following the recovery of Ivevein during rapid heating and cooling under hot pressure and internal stresses in extruded bodies, the latter are allowed to anneal in a muffle furnace, bringing the temperature to 1500 ° C and then slowly cooling for 1-2 hours. The wear resistance and: the mechanical strength of corundum bodies increases significantly.
Оиисанным 1методом можно приготовл ть беспористые издели любой требуемой форЛГы, например колеса или иилиндр1п и дл правки абразивных кругов, стеклорежущие и другие режущие инструменты, вакуу-мную корундовую керамику и т. н. материалы.With the help of the first method one can prepare non-porous products of any desired type, for example wheels or cylinders and for dressing abrasive wheels, glass cutting and other cutting tools, vacuum corundum ceramics and so on. materials.

и улучшени качества продукции, корундовые зерна подвергают травлению раствором хромпика, прессуют при температуре около 1650° под давлением 150-300 кд.см с последующим отжигом.and to improve product quality, corundum grains are etched with a solution of chromicum, pressed at a temperature of about 1650 ° under a pressure of 150-300 kd cm, followed by annealing.
