METAL-OXIDE SYSTEM THERMISTOR

摘要

The metallic oxide based materials for thermistors are composed of 27.86-41.85 wt.% manganese carbonate, 6.17-10.97 wt.% nickel oxide, 0-47.02 wt.% zinc oxide, 0-8.97 wt.% cobalt oxide, 4.13-51.14 wt.% iron oxide and 0.23-3.09 wt.% titanium oxide (titania). The thermistor material is prepared by milling the oxides with zirconia ball and distilled water as media and sintering the metallic oxide mixture at 1000-12000 deg.C through eutectic reactions.
