Refractory crucibles made of calcium oxide are tested for resistance to molten copper, nickel, cobalt, and slag. A refractory based on CaO and a ceramic bond does not enter into chemical reaction with molten copper, nickel, and cobalt; however, it do

The ceramic strength is shown to increase with decrease in porosity and decrease in grain size of polycrystals. In sintering, the material porosity decreases and the grain size increases. A relation between the ceramic strength and the kinetic parame

It is established that in order to increase the atmospheric resistance of compacts from lime and lime-periclase clinkers the temporary binder should contain high-molecular-weight resin and fatty acids, which form water-insoluble salts on the CaO surf
