High Alumina Fibers and Boards

Most commonly used in electric kilns capable of heating to 1800C as hot face linings. Prairie Ceramics has designed & shop or field installed linings for many different brands of furnaces including CM Furnaces, Thermolyne, Deltech, Lindberg, Nabertherm, Keith Kilns, Thermcraft, Mellen and Harper International.

We stock and sell the following materials

1700C & 1800C board. Alumina insulation board that is rigid and around 25 PCF density. Used for hot face linings for low mass furnaces. Prairie Ceramics stocks both boards and makes custom parts and insulation kits for furnaces.

Alumina blankets. 80 & 95% Alumina. We use this primarily for lightweight linings for operating temperatures below 1600C. These blankets also have good resistance to chemical attack for firing environments such as Piezo ceramics.

Alumina modules. Modules made from high alumina fibers used for relining kilns.

Prairie Ceramics has done extensive research with our internal kilns on lining materials and material combinations. We are experts in restoring and repairing existing linings.
