High temperature Refractory Mullite kiln shelves for sinter magnetic material
Mullilte kiln shelves is widely used in magentic materials and powder metallurgy and ceramic industry .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 wash is a layer of material between your pots and kiln shelves protecting your kiln shelves during glaze firing preventing glazes from sticking to your shelves. Unglazed pots can stick to the kiln shelf if the clay body vitrifies. Kiln wash is made of silica sand, alumina hydrate and kaolin. You can mix your own kiln wash or purchase.
We also recommend applying kiln wash to the brick on the bottom of the kiln to prevent from glaze drip damaging the soft brick.
If you are planning to rotate / flip your shelves over every few firing, you'll need to scrape and grind all the kiln wash from the bottom side first. Failing to do so will cause kiln wash particles to fall into the pots below and ruin the glaze effect.
1). low thermal expansion
2). large specific heat capacity
3). high specific surface area
4). low pressure drop
5). small thermal resistance
6). good thermal conductivity
7). good heat-shock resisting ability
