Abstract

The invention discloses a novel environment-friendly and energy-saving growth method of large-sized blocky information storage ferroelectric single crystals. The method comprises the following steps: heating an information storage ferroelectric single crystal raw material solution to realize the saturation equilibrium; seeding; transforming; carrying out programmed freezing growth; and performing post-treatment and heat crystal transferring. A single crystal mother liquid bottle does not need to be protected by protective gas and internal and external pressure balance can be controlled automatically in a liquid sealing way by using paraffin oil; air circulation between inside and outside is isolated by the paraffin oil and the temperature balance can be maintained precisely. According the method, the large-sized blocky information storage ferroelectric single crystals grow out indirectly; the manufacturing procedure is simple, the raw materials are simple and cheap, waste liquid is recyclable, no pollution or emission of the three wastes is caused; energy is saved since the crystals grow almost at room temperature; environmental friendliness is realized by virtue of growth in an aqueous solution; the manufacturing cost is low.

Description

technical field [0001] The invention relates to a manufacturing technology of a novel molecular ferroelectric information storage single crystal, in particular to an environment-friendly and energy-saving growth method of a novel large-size bulk information storage ferroelectric single crystal. Background technique [0002] Ferroelectric materials are an indispensable intelligent material for modern information storage, microelectronics, remote sensing, laser, etc., which are related to national economy and national defense. And because of its special dipole arrangement structure and the characteristics of integrating light, electricity, magnetism, heat and force, it has a special application prospect that cannot be replaced by any material, and can meet the special requirements of the rapid development of high integration in the future. . Currently, the number of widely used ferroelectric materials is very limited and focuses on inorganic oxides such as BaTiO 3 , PbTiO 3...
