Around a maximum of1500c for porous alumina and 1750 for dense alumina depending upon the grade used.
Ceramic bonding materials are available to join ceramic to ceramic and these can work well at temperatures over 1000c however, where possible it is always better to use a single piece ceramic or to join several pieces together during the manufacturing process prior to the final firing of the parts.
Ceramics are weak in tension environments but with careful design they can be used in some cases. If a ceramic is to be subject to tension loading then please discuss this with us.
Some ceramics can withstand considerable thermal shock whilst others are more prone. Pre heating or gentle temperature gradients are always a good idea if possible as this will help increase the life of the ceramic.
In situations where you need high temperature, chemical, wear or electrical properties then ceramics will often out perform metal parts. In many cases the ceramic will also prove to be more cost effective in these environments.
