Application of a Mechanoacoustic Method for Preparing a Multicomponent Charge for Producing Ceramics from Aluminosilicate Raw Materials

Abstract

The efficiency of using a mechanoacoustic method for preparing a multicomponent charge for producing ceramics from highly dispersed aluminosilicate raw materials is evaluated. The influence of ultrasonic dispersion and mechanical activation on the dispersed phase structural state is evaluated using x-ray diffraction analysis based upon changes in the size of particles and crystallites that make up an aggregate. It is established that with the help of mechanoacoustic treatment in powder represented by a mixture of differently active particles it is possible to achieve maximum structural homogeneity by reducing the size of local inhomogeneities. It is shown that use of montmorillonite as an additive to a charge in combination with mechanical-acoustic treatment reduces the sintering temperature and makes it possible to prepare ceramic with a more uniform structure and high strength.
