Preparation method of manganese-nickel-cobalt-lithium-oxygen thermal sensitive ceramic material
The invention relates to a preparation method of a manganese-nickel-cobalt-lithium-oxygen thermal sensitive ceramic material, which comprises the following steps: preparing analytically pure MnSO4.H2O, CoSO4.7H2O and NiSO4.6H2O into a 1.2 M/L mixed solution, adding a precipitator, regulating the pH value with ammonia water, filtering, washing and drying to obtain powder Mn0.4Co1-xNi0.6 (CO3)2-X, and grinding the powder Mn0.4Co1-xNi0.6 (CO3)2-X and analytically pure Li2CO3 to obtain powder, after calcining the obtained powder, mixing the powder with LiF, grinding, molding to obtain a wafer, carrying out isostatic cool pressing on the wafer, sintering in air to obtain a ceramic wafer, coating silver paste on two sides of the ceramic wafer, and annealing at 835 DEG C for 20 minutes to obtain the manganese-nickel-cobalt-lithium-oxygen thermal sensitive ceramic material.
本发明涉及一种锰镍钴锂氧热敏陶瓷材料的制备方法，该方法以分析纯MnSO4·H2O，CoSO4·7H2O和NiSO4·6H2O配制成浓度为1.2M/L的混合溶液，加入沉淀剂，用氨水调节pH，过滤，洗涤并干燥以获得粉末Mn0.4Co1‑xNi0.6（CO3）2‑X，再将粉末Mn0.4Co1‑xNi0.6(CO3)2‑X和分析纯的Li2CO3研磨，得到粉体，将得到的粉体煅烧后，与LiF混合研磨后成型，得到圆片，再将圆片冷等静压，在空气中进行烧结，得到陶瓷片，再将陶瓷片两面各涂银浆，并在温度835℃退火20min处理，即得到锰镍钴锂氧热敏陶瓷材料。
