Sintering and Mechanical Properties of High-Porosity Ceramics Based on Diatomite

Article Preview

Abstract:

The study is devoted to the study of the mechanical properties of penodiatomite ceramics. Dynamics of changes in the dynamic moduli of elasticity of highly porous (up to 70%) diatomite ceramics from the annealing time at temperatures of 800-1000 °С has been experimentally studied. The values of the activation energies of the change in the modulus of elasticity (Wa = 0.22-0.24 eV) were measured for high-temperature annealing (800-1000 °С). The change in the phase composition of the samples under the influence of annealing is demonstrated.
