Study on thermal expansion and thermal shock resistance of MgOPSZ
Solid State Ionics 121(1999)61-65，-0001，（）：
The thermal expansion characteristics of MgO partially stabilized zirconia (MgO-PSZ) electrolytes are studied by dilatometric technique. It is found that the phase transformation of MgO-PSZ from onoclinic to tetragonal takes place in two temperature ranges of 460-8308C and 1150-11808C. The volume shrinkage associated with these phase transformations plays an important role for the thermal shock resistance. With heat-treatment at 13008C for 2h and at 10008C for 6-8h, the thermal shock resistance of the MgO-PSZ electrolyte tube can be greatly improved.
