Abstract
The disclosure relates to a co-current co-precipitation method of CoNiOthermistor powders. The method comprises the steps of mixing, stirring, precipitating, aging, suction filtration, washing and drying firstly using nickel nitrate and cobalt nitrate as raw materials to obtain cobalt hydroxide, and then calcining in a tubular furnace at an inert atmosphere to prepare CoNiOnano powders. The method has the advantages of simple operation, low cost, short cycle, high yield and no environmental pollution, and further oxidization of the CoNiOnano material into NiCoOthermistor powders can be effectively avoided through selection and adjustment of calcination process parameters and inert atmosphere. A high-precision, fast-response and small-volume temperature sensor material can be prepared from CoNiOthermistor powders obtained by the method of the disclosure.
