Method for preparing zinc sulfide ceramic material from coal coking desulfurization waste liquid
The invention relates to a method for preparing a zinc sulfide ceramic material from coal coking desulfurization waste liquid. According to the method, desulfurization waste liquid and zinc acetate are adopted as raw materials, and the preparation method comprises the steps of mixing and stirring, constant-temperature heating, filtering, drying, vacuum hot-pressing sintering, high-temperature annealing and the like. The zinc sulfide ceramic material obtained by the method can be used in the field of thermistors; the zinc sulfide ceramic is high in sensitivity, the resistance temperature coefficient is 10-100 times greater than that of metal, the temperature change of -50 DEG C to 100 DEG C can be detected; the product is small in size, capable of measuring the temperature of gaps, cavitiesand blood vessels in organisms which cannot be measured by other thermometers, easy to process into complex shapes, capable of being produced on a large scale, good in stability and high in overloadcapacity; and the zinc sulfide ceramic material prepared through the method has high compactness and hardness and good corrosion resistance. Based on the idea of changing waste into valuables, the method is beneficial to energy saving, water saving and resource recycling, effectively enhances the resource utilization ratio, increases the economic production benefit, and provides an innovative ideafor energy saving and emission reduction.
