  • Patent number: 11390535
    Abstract: The disclosure relates to a co-current co-precipitation method of CoNiO2 thermistor 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 CoNiO2 nano powders. The method has the advantages of simple operation, low cost, short cycle, high yield and no environmental pollution, and further oxidization of the CoNiO2 nano material into NiCo2O4 thermistor 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 CoNiO2 thermistor powders obtained by the method of the disclosure.

  • Patent number: 11364481
    Abstract: A system and method for producing a modified coal ash involves collecting a bulk quantity of such coal ash, generally after it has been produced or landfilled, or is otherwise at temperatures closer to ambient, as opposed to power plant operational temperatures. In one possible implementation, the method herein involves removing carbon from the coal ash, such removal occurring by exposing the carbon to indirect heat, that is, externally-applied heat. For coal ashes with higher ash content. This removal is accomplished by subjecting the coal ash stream to heat, in one implementation, ranging between 850° F. and 1200° F., and such heat exposure occurring from about 10 minutes to about 30 minutes. The range of exposure time for the coal ash is determined so as to reduce the LOI from its initial level to a level acceptable for intended re-use or recycling. In one application, the LOI of carbon in the ash is reduced to 3% or less carbon.
