Abstract: The voltage nonlinear resistive element 10 includes a resistor 14 containing a joined body 12 in which a zinc oxide ceramic layer 12a composed mainly of zinc oxide and having a volume resistivity of less than 1.0×10−2 Ωcm is joined to a rare-earth metal oxide layer 12b composed mainly of a rare-earth metal oxide, and a pair of electrodes 16 and 18 disposed on the resistor 14 such that an electrically conductive path passes through a junction between the zinc oxide ceramic layer 12a and the rare-earth metal oxide layer 12b. In this element 10, the zinc oxide ceramic layer 12a of the joined body 12 has a lower volume resistivity than before. This can result in a lower clamping voltage in a high electric current region than before.

Abstract: A mixed powder was prepared by weighing Yb2O3 and SrCO3 in such a way that the molar ratio became 1:1. The resulting mixed powder was subjected to uniaxial pressure forming, so as to produce a disc-shaped compact. The compact was heat-treated in an air atmosphere, so that a complex oxide was synthesized. The resulting complex oxide was pulverized. After the pulverization, a slurry was taken out and was dried in a nitrogen gas stream, so as to produce a synthesized powder material. The resulting synthesized powder material was subjected to uniaxial pressure forming, so as to produce a disc-shaped compact. The resulting compact was fired by a hot-press method, so as to obtain a corrosion-resistant member for semiconductor manufacturing apparatus. The resulting corrosion-resistant member was made from a SrYb2O4.
