A barium titanate crystal memory device

The ferroeleetrie phenomenon is described and compared with ferromagnetic behavior. The crystal lattice structure of barium titanate is described, and the tetragonal phase accounts for the ferroelectric behavior. Terms to be used in describing ferroeleetric characteristics are defined. The method of growing barium titanate crystals in a potassium fluoride melt is described briefly. The fabrication of the crystal unit is described, including the mounting in a container similar to that used for transistors. A series of standard sizes of crystal units is proposed.
