Molecular formula : CAS :
nature : also known as the refractory degrees. Characterization of objects without melting heat resistance performance indicators. Refractoriness material is not of the physical constants, but a technical indicators, it's determined by the chemical composition of materials, dispersion, the liquid in which the proportion of liquid viscosity and determined. Determination of refractoriness : Test materials will be made provisions size of truncated triangular cone, in a certain warming speeds heating, because of their weight and gradually bend down and try to bend down to the cone apex of its contact with the chassis that is the temperature at which the test materials refractoriness.
