Preparation method of ceramic substrate
The invention discloses a preparation method of a ceramic substrate, and relates to the technical field of ceramic substrate processing. The preparation method of the ceramic substrate comprises the following steps: mixing titanium isopropoxide sol and barium carbonate sol to form amorphous phase barium titanate precursor gel, then adding sodium methyl silicate, bismuth nitrate pentahydrate and yttrium isopropoxide to carry out hydrothermal reaction to prepare barium titanate-based ceramic powder, and then carrying out tape casting on the ceramic powder to obtain a ceramic sheet, and finally, adding the barium titanate-based ceramic sheet into a double-sided grinding machine prepared with grinding liquid, and carrying out coarse grinding and fine grinding, thereby obtaining the product. The preparation method of the ceramic substrate is low in cost and simple in preparation, and the barium titanate-based ceramic powder is high in purity, small and uniform in particle size, high in dielectric constant, low in dielectric loss, high in Curie temperature and wide in Curie temperature region; the surface of the ceramic substrate is flat, smooth, free of damage and not prone to brittle failure.
本发明公开一种陶瓷基片的制备方法，涉及陶瓷基片加工技术领域。本发明公开的陶瓷基片的制备方法为：将异丙醇钛溶胶和碳酸钡溶胶混合，形成非晶相的钛酸钡前驱物凝胶，然后加入甲基硅酸钠、五水硝酸铋和异丙醇钇进行水热反应，制得钛酸钡基陶瓷粉体，再对陶瓷粉体进行流延成型，得到陶瓷片材，最后对钛酸钡基陶瓷片材加入到配制有研磨液的双面研磨机中进行粗磨和精磨，即可。本发明提供的陶瓷基片的制备方法，成本较低，制备简单，且钛酸钡基陶瓷粉体的纯度高、颗粒尺寸较小且均匀，并具有高介电常数、低的介电损耗、较高的居里温度和较宽的居里温度区域；陶瓷基片表面平整、光滑、无损伤，且不易脆断。
