Repton Texture Surface

REPTON setter tiles, kiln furniture, and special fixtures are lightweight, ridge, and high strength ceramics that resist distortion and spauling, even when thermal cycled many times. They are available with a smooth or a unique textured surface that permits pinpoint contact with the load. Sticking can be eliminated as well as providing a surface that breathes, allowing gasses from the ware to escape.

Applications include firing ceramic capacitors, SOFCs, PZTs, hard and soft ferrites, co-fired substrates and powdered metals. REPTON is available in a wide range of compositions that include a range of alumina, mullite/alumina, zirconia, cordierite, magnesia, and aluminum titantate.

Construction: Repton tiles and shapes are gel cast to precise and consistent dimensions and then high fired to retain stability. In addition to flat setter tiles, this process can be used formed saggers, trays, crucibles, and tubes.

Sizes: Standard sizes are up to 13" x 13" - Custom shapes up to 24" x 24" and thickness from 1 to 50 mm. Note that larger sizes require thicker tiles.

Surface Finish: Smooth or textured to reduce sticking and allow for product out gassing. A zirconia coating can be applied and fired on the surface to reduce chemical interaction.

Repton Texture Surface (also available with smooth surface)	Compositions: Alumina, Mullite/Alumina,Zirconia, Cordierite, Magnesia, AluminumTitantate, Yttria, and Special Compositions Porosity: 0 to 70%
