トルマリンとSr-フェライトの樹脂成形体の電界および磁界中での製造とその特性 Preparation and Properties of Tourmaline and Sr-ferrite Mixed Resin Hardened under Electic and Magnetic Fields
The molded tourmaline/Sr-ferrite pellets is prepared by mixing tourmaline and Sr-ferrite powders with polyester resin and hardened under electric and magnetic fields. The piezoelectric-g-constant and magnetic flux density of the molded pellets were investigated.<BR>Tourmaline particles in the molded pellet oriented toward the electric field direction for electric field strengths more than 0.5kV/mm, and the piezoelectric-g-constant of the molded pellets increased for any increse in the electric field strength. Also the piezoelectric-g-constant of the molded pellet showed a sharp increase when the thickness of the molded pellet became less than 1mm.<BR>The magnetic flux density of molded tourmaline/Sr-feffite pellet hardened under magnetic field depended on the Sr-ferrite content.
