%X Microstructure of reaction sintering of ZnAl2O4 at 1500℃ by hot-pressing(HP) and pulse electric current was investigated. The results indicated that the existed cracks in sintered body were caused by structure mismatch. lt is the evidence that periodical temperature field existed during pulse electric current sintering of nonconductive materials.The distance between high temperature areas was related to die diameter.
