Description

алюмохромфосфатного св зук аего не должно превышать 20 вес.%, так как в противном случае смесь плохо прессуетс  и заготовки получаютс  неудовлетворительного качества. При содержании св зующего меньше 5 вес.%The aluminum chromophosphate bond should not exceed 20 wt.%, otherwise the mixture will not compress well and the billets will be of unsatisfactory quality. When the content of the binder is less than 5 wt.%

Сравнительные свойства материалов, полученных из известной и предлагаемой шихты 658 54 наблюдаетс  снижение прочности материала . HeKOTOjxje свойства полученного электроизол ционного материала на основе нитрида бора приведены в таблице.Comparative properties of materials obtained from the known and proposed mixture 658 54 a decrease in the strength of the material is observed. HeKOTOjxje properties of the obtained electrical insulating material based on boron nitride are given in the table.

Предел прочности при сжатии, кг/мм.3,8 Температура начала Заметного окислени  при нагреве на воздухе ,с - .1200 Удельное электросопротивлеКак видно из таблицы, материал, полученный из предлагаемой шихты, обладает более высокой механической прочностью,по сравнению с известным.Compressive strength, kg / mm.3.8 The temperature of onset of noticeable oxidation when heated in air, s - 1200 The specific electrical resistance As seen from the table, the material obtained from the proposed mixture has a higher mechanical strength than the known one.

Кроме того, полученный материал не смачиваетс  расплавом железа и сплавами на его основе.In addition, the material obtained is not wetted by molten iron and alloys based on it.

Материал обладает также высокой стойкостью к окислению.The material is also highly resistant to oxidation.
