Strengthening of forsterite ceramic microarticles using impregnation in salt solutions

The results of experiments on hardening miniature bushings with an outer diameter of 1.2 - 3.5 mm made of forsterite ceramics by impregnation in salt solutions are presented. It is shown that an increase in the temperature of the first firing and a decrease in the duration of impregnation of semi-finished products leads to an increase in strength from 47% to 2.7 times, depending on the size of the products. The mathematical processing of the experimental results was carried out by the spline interpolation method. Tab. 2, ill. 2, bibliography: 3 titles.
