Title: Dielectric electrode material for plasma generation
Inventor: DOUSAKA KENJI
IPC: H05H1/24
Filed: 2000-10-02
Abstract: PROBLEM TO BE SOLVED: To obtain a dielectric electrode material for plasma generation having a high dielectric constant and excellent mechanical strength to dielectric breakdown. SOLUTION: At least either of Ba and Ca is selected for an A site of perovskite ceramics expressed by the chemical formula ABO3 and Ti is selected for a B site and MgO is dispersed therein at 5 to 30 vol.%. The progression of the crack at the crystal grain boundaries of its matrix is obstructed by the MgO dispersed into the grain boundaries or the progression direction is changed by the MgO, by which the destruction energy is relieved and the mechanical strength is improved. The MgO dispersed at the grain boundaries exhibits a spinning effect on the matrix to suppress the grain growth of matrix crystal grains and therefore the crystalline particle sizes of a sintered compact are reduced and the routes of the crack progression are complicated, by which the destruction energy is relieved and the mechanical strength is improved.
