Ceramic Tile Thermal Expansion

Almost any fired ceramic object experiences expansion as it is heated and contraction as it is cooled.

Ceramic tile thermal expansion.

The coefficient of thermal expansion or clte coefficient of linear thermal expansion. There is a rich mans and poor mans way to fit glazes the latter might be better. Understanding thermal expansion in ceramic glazes description. With a sintering temperature of 950 c the miba based glass ceramic tiles demonstrated high mechanical performance capable of satisfying ceramic wall tile requirements i e bending strength 12 mpa and thermal expansion coefficient 9 10 6 c schneider 1991.

The lower line is the glaze. Potters can learn from how glazes are fit on ceramic tile. Fine ceramics also known as advanced ceramics have low coefficients of thermal expansion less than half those of stainless steels. The center line is the engobe.

These are thermal expansion curves for body engobe and glaze from a dilatometer a device that measures it against increasing temperature. Expansion values vary depending on the material being heated. The linear expansion of a heated solid or liquid is measured by. The upper line is the body.

The coefficient ratio of thermal expansion indicates how much a material expands per 1 2 2 rise in temperature.
