Ceramic Tile Thermal Expansion

Expansion values vary depending on the material being heated.

Ceramic tile thermal expansion.

Understanding thermal expansion is the key to dealing with crazing or shivering. There is a rich mans and poor mans way to fit glazes the latter might be better. The linear expansion of a heated solid or liquid is measured by. Almost any fired ceramic object experiences expansion as it is heated and contraction as it is cooled.

The lower line is the glaze. The coefficient of thermal expansion or clte coefficient of linear thermal expansion. The coefficient ratio of thermal expansion indicates how much a material expands per 1 2 2 rise in temperature. The upper line is the body.

Special thanks to reader eric p e. These are thermal expansion curves for body engobe and glaze from a dilatometer a device that measures it against increasing temperature. The coefficient of linear thermal expansion clte of any material is the change of a material s dimension per unit change in temperature. 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.
