Low-temperature NTC thermistor ceramic and preparation method thereof
The invention provides low-temperature NTC (Negative Temperature Coefficient) thermistor ceramic and a preparation method thereof. The preparation method of the low-temperature NTC thermistor ceramic comprises the following steps: raw material mixing, stirring, wet ball milling, drying detection, powder pre-sintering, grinding, granulation, compression molding and sintering. The grinding device is used in the preparation process, the dried and polymerized CaO, Mn2O3 and La2O3 mixed powder can be automatically ground to be in a clear particle state, and in the grinding process, a mortar is in a closed state, so that powder is prevented from flying out and generating loss in the grinding process, subsequent screening and detection are facilitated, and the production efficiency is improved. The material loss is reduced, and meanwhile manpower is saved.
本发明提供一种低温NTC热敏电阻陶瓷及其制备方法。一种低温NTC热敏电阻陶瓷及其制备方法包括以下步骤：混合原料、搅拌、湿法球磨、干燥检测、粉料预烧、研磨、造粒、模压成型、烧结。本发明通过本发明在制备过程中通过使用研磨装置，可以自动对烘干后聚合起来的CaO、Mn2O3、La2O3混合粉末进行研磨，使其研磨成颗粒分明的状态，并且在研磨过程中，研钵为内部封闭的状态，防止研磨时有粉末飞出，产生损失，便于之后的过筛和检测，减小了物料的损失，同时节省了人力。
