Изобретение относитс The invention relates to
к производству абразивного инструмента.to the production of abrasive tools.
Известна керамическа св зка, используема дл изготовлени абразивного инструмента из карбида кремни .The famous ceramic bond used to make silicon carbide abrasive tools.
Однако эта св зка с температурой обжига, равной 950°С, нетехнологична из-за необходимости использовани дополнительного оборудовани .However, this bond with a firing temperature of 950 ° C is not technological because of the need to use additional equipment.
Цель изобретени - повышение реакционной способности св зки.The purpose of the invention is to increase the reactivity of the binder.
