Preparation method of strontium titanate heat source pellet
The invention relates to a preparation method of a strontium titanate heat source pellet, which comprises the following steps: mixing strontium carbonate and titanium dioxide in a wet mixing manner to obtain slurry; drying the slurry, and then carrying out first heat treatment to obtain a mixture; performing cold press molding on the mixture to obtain a green body; and carrying out second heat treatment on the green body to obtain the strontium titanate pellet. In the preparation method provided by the invention, the strontium titanate conversion process is reduced into three steps of mixing, drying and heat treatment, so that the technological process is greatly reduced. Moreover, cold press molding can be carried out in an oil press, so that related complex equipment and precise operation are omitted, and the production efficiency is improved.
本发明涉及钛酸锶热源芯块的制备方法，包括：采用湿法混合方式来混合碳酸锶和二氧化钛，得到浆料；对所述浆料进行干燥，然后进行第一热处理，得到混合物；对所述混合物进行冷压成型以获得生坯；以及，对所述生坯进行第二热处理，以得到所述钛酸锶芯块。在本申请的制备方法中，将钛酸锶转化过程缩减为混合、干燥、热处理三个步骤，大大缩减了工艺流程。并且，冷压成型可在油压机中进行，省去了相关的复杂设备和精密操作，提高了生产效率。
