FERROELECTRICS KH2PO4 AND ANTIFERROELECTRICS NH4H2PO4 NANOCRYSTAL GRAIN SUBSTANCE INCORPORATED IN POROUS MATERIAL

摘要

The present invention provides a porous material for uniformly growing nanocrystal powders of KH ₂ PO ₄ (KDP) and NH ₄ H ₂ PO ₄ (ADP) to produce ferroelectrics and antiferroelectrics. The present invention relates to a composite dielectric using nanocrystals and a method of manufacturing the same. The composite dielectric manufacturing method includes the steps of preparing a plate-shaped porous body having a plurality of ultra-fine pores, removing and washing alkaline ions from the porous body, and washing the porous body at a predetermined temperature. Drying for a predetermined time, and incorporating an aqueous solution of either ferroelectric or antiferroelectric material having a predetermined dielectric constant into the pores of the porous body to grow nanocrystals. As a result, nanocrystal grains of ferroelectrics and precipitation dielectrics embedded in the porous body can be easily manufactured, so that the mechanical strength can be maintained while utilizing the characteristics of the nanocrystals. Because of its characteristics, its use is extended to MICROWAVE, far-infrared absorber, scattering material of infrared rays and visible light, and it has the effect of maximizing its utility.
