Plates

Uses: These can be used as a substrate to place your crucibles on or as high temperature stacking furnace wear (up to 5 levels high is recommended for higher temperature applications).

Substrates are flat but not machined, machined plates are available on request 
Laser cutting of alumina plates available (up to 2 mm thickness)
Guaranteed to not react or contaminate your work and suitable up to 1,750°C  (1,650°C as stacking furnace wear)
Please note the larger plates should be supported well at high temperatures to avoid Creep (warping)
