99% Alumina ceramic round plates with a hole
Ceramic round plates:
Due to the high temperature resistance of alumina ceramics, round standard plates can be used as a sintering base for various components such as crucibles. Alternatively, they serve as lids for round crucibles. If evaporation or temperature measurement inside the crucible is required, round plates with holes are used. In addition, the panels can be used as raw material for further processing.
