Conclusions
It has been established that the traditional parameters of the preparation of cast slips made from stabilized ZrO2 are unsuitable for the experimental composition ZrO2+25% CaO since the time required for washing of the hammered-on iron is sharply increased.
The behavior of the hammered briquette of the experimental composition depends on the aggregation of fine particles having a well-developed surface and its dissolution in solutions of HCl, leading to the formation of a liquid solvated shell around a particle and thus preventing the deposition of the suspensions and the removal of iron chloride.
Shortening the duration of the milling of the material from 21 to 4 h helps to speed up the deposition of the suspensions as a result of the coarser particle aggregates and the better removal of the iron chloride. In this case the working properties of the articles are not impaired.
