本文介绍了生产球形锆钛酸铅（PZT）纳米粒子的电流体动力雾化（EHDA）过程中，以使油墨适用于喷墨打印应用。以不同浓度（0.1 - 0.6 M）的PZT溶胶为起始材料。使用两种不同的加热系统，气体加热和直接加热，以除去溶剂，减小粒度并稳定PZT颗粒。考察了液体流速、溶胶浓度和加热系统温度等因素对颗粒尺寸的影响。使用在520°C下直接加热、0·2 M前体溶胶、0·2 mL h-1的流速和3 kV cm-1的场的优化处理参数，合成直径为100-300 nm的颗粒。在300°C下稳定后，将颗粒悬浮在PZT溶胶中以产生适用于喷墨印刷的油墨。
This paper describes the production of spherical-shaped lead zirconate titanate (PZT) nanoparticles by the electrohydrodynamic atomisation (EHDA) process in order to make inks suitable for ink jet printing applications. PZT sols with different concentrations (0·1–0·6 M) were used as starting materials. Two different heating systems, gas heating and direct heating, were used in order to remove the solvent, reduce the particle size and stabilise the PZT particles. Several aspects have been considered, such as liquid flow rate, sol concentration and heat system temperature, and their influence on the particle dimension is determined. Using optimised processing parameters of direct heating at 520°C, 0·2 M precursor sol, flow rate of 0·2 mL h−1 and field of 3 kV cm−1, particles of 100–300 nm in diameter were synthesised. Following stabilisation at 300°C, the particles were suspended in a PZT sol to produce an ink suitable for ink jet printing.
