<p>Spray-coating materials having a high heat-resistance and thermal conductivity for the surface protection of materials. The spray-coating material consists of 8-35 wt. % magnesium oxide MgO or calcium oxide CaO, 2-10 wt. % of beryllium oxide BeO and 55-90 wt. % of aluminum oxide Al2O3, zirconium dioxide ZrO2, silicon dioxide SiO2, chromic oxide Cr2O3 and titanium dioxide TiO2. The spray-coating material of the invention can be employed to advantage, for example, in the chemical industry and in metallurgy.</p> |
