Ceramic Tile Thermal Expansion

These are thermal expansion curves for body engobe and glaze from a dilatometer a device that measures it against increasing temperature.

Ceramic tile thermal expansion.

The lower line is the glaze. The linear expansion of a heated solid or liquid is measured by. Potters can learn from how glazes are fit on ceramic tile. Understanding thermal expansion in ceramic glazes description.

There is a rich mans and poor mans way to fit glazes the latter might be better. The coefficient of linear thermal expansion clte of any material is the change of a material s dimension per unit change in temperature. The coefficient of thermal expansion or clte coefficient of linear thermal expansion. Expansion values vary depending on the material being heated.

The upper line is the body. Almost any fired ceramic object experiences expansion as it is heated and contraction as it is cooled. 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. Fine ceramics also known as advanced ceramics have low coefficients of thermal expansion less than half those of stainless steels.
