High strength no deformation corosion resistance mullite kiln shelf
1. Details
Mullilte kiln shelf is widely used in electronic industry and powder metallurgy .It plays roles of kiln shelf in high temperature furnace.
Kiln shelves should be stored standing up on their edges. Storing them flat makes it more possible for them to break or cracks. Keep shelve dry. If they do get wet (e.g., after applying kiln wash), heat them slowly and soak for a few hours at 300° F.
