Foaming ceramic based on copper-molybdenum tailings and preparation method thereof
The invention discloses foamed ceramic based on copper-molybdenum tailings and a preparation method of the foamed ceramic, and the foamed ceramic comprises the following raw materials in parts by weight: 55-80 parts of copper-molybdenum tailings, 5-20 parts of potassium feldspar, 25 parts of a fluxing agent, 0.5-1.5 parts of a foaming agent and 1-3 parts of a foam stabilizer. Wherein the fluxing agent is composed of sodium carbonate and waste glass, and the sodium carbonate accounts for 12-32% by mass of the fluxing agent; the foaming agent is composed of dolomite and silicon carbide; the foam stabilizer is calcium phosphate. The preparation method comprises the following steps: ball-milling and mixing the raw materials by a dry method, uniformly paving the mixture in a mold, and finally sintering at 940-990 DEG C to prepare the ceramic. The obtained foamed ceramic is small in density, high in compressive strength and low in heat conductivity coefficient, the sintering temperature is reduced to 940-990 DEG C while high-doping-amount utilization of the copper-molybdenum tailings is achieved, energy consumption in the sintering process is reduced, and good economic benefits and social benefits are achieved.
本发明公开了一种基于铜钼尾矿的发泡陶瓷及其制备方法,按重量份数计,发泡陶瓷原料包括以下组分:铜钼尾矿55~80份、钾长石5~20份、助熔剂25份、发泡剂0.5~1.5份和稳泡剂1~3份;其中:所述助熔剂由碳酸钠和废玻璃组成,碳酸钠在助熔剂中的质量百分占比为12~32%;所述发泡剂由白云石和碳化硅组成;所述稳泡剂为磷酸钙。通过将原料干法球磨混合后均匀平铺至模具内,最后在940~990℃温度下烧结制备得到。本发明所得发泡陶瓷密度小、抗压强度高、导热系数低,并在实现铜钼尾矿高掺量利用的同时将烧结温度降低至940~990℃,减少了烧制过程中的能耗,具有较好的经济效益和社会效益。
