Ceramic Tile Thermal Expansion

Understanding thermal expansion is the key to dealing with crazing or shivering.

Ceramic tile thermal expansion.

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. The center line is the engobe. 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. 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 coefficient ratio of thermal expansion indicates how much a material expands per 1 2 2 rise in temperature. Expansion values vary depending on the material being heated.

These are thermal expansion curves for body engobe and glaze from a dilatometer a device that measures it against increasing temperature. Fine ceramics also known as advanced ceramics have low coefficients of thermal expansion less than half those of stainless steels. The lower line is the glaze. Potters can learn from how glazes are fit on ceramic tile.

The upper line is the body.
