  • Publication number: 20140157558
    Abstract: Plastic capillaries are used as a reaction template; firstly, sol-PZT is prepared; then, PZT nanometer powder is added into the sol-PZT and blended uniformly to form suspension, the plastic capillaries are put into a quartz tube, the gaps between the capillaries and the gaps between the quartz tube and the plastic capillaries are filled with paraffin and solidified to a required array shape, the quartz tube is dipped into the suspension, after full absorption, the rest suspension is poured into the quartz tube and filtered from the other end, so that the suspension is pumped into the plastic capillaries until the capillaries are full of suspension. The quartz tube is dried until no excessive liquid component and then taken out to be dipped, filtered and dried; removal of template and crystallization heat treatment is then performed for the dried container.
