Analysis of the development of microscopic residual stresses on quartz particles in porcelain tile

Effect of quartz particle size on the mechanical behaviour of porcelain tile subjected to different cooling rates

“…A previous study by the authors 14 showed that the microscopic residual stresses exhibited by quartz particles were strongly affected by two factors: (1) the advanced state of dissolution of the smallest quartz particles, which modified the nature of the particle-matrix interface by increasing the state of stress on the particles; (2) the presence of a significant fraction larger than the critical particle size reduced the state of stress. It was further verified that the quartz in the porcelain tile matrix displayed an average coefficient of linear thermal expansion similar to that of the c-lattice parameter.…”

Sinterização de porcelanatos com fluxo viscoso: Uma revisão

“…O papel da transformação do quartzo β ↔ α é amplamente reconhecido, não apenas para possíveis rupturas durante o resfriamento [60][61][62][63][64], mas também pelo seu efeito nas propriedades elásticas e tensões residuais [61,[64][65][66].…”

Optimization of the technological properties of porcelain tile bodies containing rice straw ash using the design of experiments methodology

“…This type of tile has been widely used as floor and wall covering and more recently in ventilated facades [3]. In recent years, the demand for porcelain stoneware tile has grown significantly compared to that of other ceramic construction materials, growth being particularly attributed to porcelain tile's enhanced performance characteristics, especially regarding water absorption, frost resistance, bending strength, and wear resistance [2][3][4][5].…”
