Lead metaniobate seed crystal and preparation method and application thereof
The invention discloses a preparation method of lead metaniobate seed crystals, which comprises the following steps: mixing PbO and Nb2O5 to obtain mixed powder; mixing the mixed powder with KCl, and then reacting at 850-1150 DEG C for 1-4 hours to obtain a reactant; and washing and drying the reactant to obtain the lead metaniobate seed crystal. The method is simple in step and convenient to operate, a large number of high-quality lead metaniobate seed crystals can be prepared within a short time, and the production efficiency is improved. The invention also discloses a lead metaniobate seed crystal, and the lead metaniobate seed crystal is used as a key raw material for preparing the lead metaniobate textured ceramic, so that the performance and the stability of the ceramic are remarkably improved. The invention also discloses application of the lead metaniobate seed crystal to preparation of lead metaniobate textured ceramic, the Curie temperature of the lead metaniobate textured ceramic is 487-512 DEG C, and the lead metaniobate textured ceramic has excellent high temperature resistance.
本发明公开了一种偏铌酸铅种晶的制备方法，包括如下步骤：将PbO和Nb2O5混合，得到混合粉末；将所述混合粉末与KCl混合，然后在850～1150℃下反应1～4h，得到反应物；将所述反应物水洗干燥得到偏铌酸铅种晶。该方法步骤简单，操作方便，可以在较短时间内制备出大量高质量的偏铌酸铅种晶，提高生产效率。本发明还公开了一种偏铌酸铅种晶，该偏铌酸铅种晶作为制备偏铌酸铅织构陶瓷的关键原料，显著提高陶瓷的性能和稳定性。本发明还公开了一种偏铌酸铅种晶用于制备偏铌酸铅织构陶瓷，该偏铌酸铅织构陶瓷的居里温度位于487～512℃，具有优异的耐高温性能。
