Conclusions 1. It was established that cylindrical products made of unglazed porcelain (ratio of diameter to height ≈1/3) which operate under compression and whose end faces are glued into metal yokes have a load-bearing capacity and reliability that are 2.8 and 3.7 times, respectively, better than the analogous characteristics when porcelain rods are loaded by flat metal supports. 2. It was shown that with an accuracy sufficient for practical purposes, the probability distribution of compressive strength of porcelain can be described as Gaussian. 3. It was proved that common properties of such nonmetallic materials as electrotechnical porcelain, glass, pyroceramics are the considerable dependence of uniaxial-compression test results on the boundary conditions, high stability of particular values of strength in case of minimum influence of the contact stresses on the obtained characteristics, similar values of the Poisson ratio and bending strength, comparable ratios of bending and compressive strength, and also the ratio of the level of rupture stresses in loading by smooth punches to the compressive strength, linear stress-strain diagrams, and the like nature of rupture in compression.
