HEAT CONDUCTIVITY OF PURE OXIDE CERAMICS,

Abstract

The values of lamda (heat conductivity) for dense specimens of ceramics made from Al2O3, MgO, and BeO, measured by the methods of stationary and regular heat regimes, differ within the limits of experimental error. The lamda of specimens with similar density depends on the character of their structure, which in turn is caused both by the method of their manufacture and by the heat treatment during annealing and their service. The values of lamda obtained in our investigation for dense ceramics of pure oxides at low temperatures (400-600C) turned out to be significantly smaller than the values given in many foreign sources.
