Refractory high temperature furnace use Mullite kiln shelves for sale
1. Product details
Mullilte kiln shelves is widely used in electronic industry and powder metallurgy .It plays roles of kiln shelf in high temperature furnace.
If you are customer who need mullite push kiln shelves in these two industry , our mullite kiln shelves will be your best option. It has high strength and high density than common mullite kiln shelves.It can bear high temperature thermal shock and high load deformation resistance.
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
Mullite are well known for their low thermal expansion and refractory character. Although mullite is available as a powder, when we use the term we are generally talking about ceramic that went into the kiln as ordinary composite of ceramic powders but emerges as a cordierite crystalline matrix (grown by the firing process tuned to its needs).
2. Features
