A method and apparatus for forming piezoelectric tubes is provided. The method includes forming a suspension (1) of ceramic particles (2) in a fluid medium (3), positioning a rod (5) in the fluid medium (3), depositing particles (2) on the rod (5) by electrophoresis, and heat-treating the deposited particles to form a piezoelectric tube by heating the deposited particles to a first predetermined temperature to solidify the particles to a surface of the rod and burn the rod, thereby leaving a tube of solidified particles closed at one end, and heating the tube to a second predetermined temperature to thereby sinter the tube to form a dense ceramic tube. The apparatus is adapted for carrying out the method. |
