What are Refractory Setter Tiles?

Refractory Setter Tiles, kiln furniture, and special fixtures are lightweight, rigid 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. Refractory Setter Tiles are available in a wide range of compositions that include a range of alumina, mullite/alumina, zirconia,cordierite, magnesia, and aluminum titantate.

Construction: Refractory Setter 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.

Porosity: 0 to 70%

Technical Data for Alumina Refractory Setter Tiles


Testing Notes:

Spalling Test: A 200 x 200 x 2 mm test specimen is supported at the corners by 25 pillars. A 50 gram weight is placed in the center and the plate and pillars are inserted and removed from a furnace at temperature. The highest temperature where no cracking occurs after 5 cycles is determined to be the Spall Resistant Temperature

Hot Creep Test: A 180 x 25 x 2 mm specimen is supported across a 160 mm span with a 35 gram load placed at the center of the specimen. The specimen is heated for 5 hours at several temperatures and the deflection in mm is measured and recorded.
