Abstract


Presented in this article studies show the investigation of ultrasound application as a new method for improvement of ceramic materials processing and their influence on mechanical properties of dried samples. Ultrasound were applied during convective and convective-microwave processes carried out in two different temperatures. Obtained results indicate increase of drying rate due to sonification and what’s more interesting they affect the material strength parameter. The experiments indicate that the effectiveness of ultrasound assist depends on the drying temperature and such dependency is observed mainy when considering dry product quality parameter.
