Abstract
The present invention has been achieved by a material for a sintering appliance which comprises a base material comprising alumina.times.silica containing from 65 to 95% by weight of Al.sub.2 O.sub.3 having formed on the surface thereof a flame-coated film comprising ZrO.sub.2 and CaO as main components, wherein the content of CaO is from 23 to 30% by weight based on the weight of the ZrO.sub.2 and CaO, the mineral composition of the main components of the coated film is calcium zirconate. Preferably the difference of thermal expansion between the base material and the flame-coated film is 0.3 or more at 1,200.degree. C.
