Influence of Stony Rocks Additives on Strengthening of Aluminosilicate Ceramics from Fusible Clays

Abstract

The paper presents the results of the research, connected with the granulometric and mineralogical compositions of fusible clay raw materials of Krasnoyarsk region - argillic and loose clay varieties. The influence of granitoid and diabase rocks stony additives on the sinterability and strength characteristics of the ceramic materials based on fusible clays is evaluated. It is found that the introduction of sintering additives into the loose fusible clay leads to the significant increase of samples strength - 50-100 MPa, while the introduction of the similar additives in the argillic clay does not influence positively on samples strength.
