Lithium niobate crystals have a number of unique properties. Lithium niobate is at the same time a ferroelectric, piezoelectric, pyroelectric, and has high nonlinearly optical and electro-optical coefficients and photorefractive sensitivity. These properties enable these crystals to be used widely in optical and acoustic devices, and photorefractive sensitivity, enhanced by doping with transitional metals, offers new possibilities of using lit...

A new method of production of high-temperature dielectric crystals, including cubic zirconia, glasses and melted ceramic materials, is discussed. The method is based on direct induction melting in a cold container. The physical fundamentals of the technology and equipment are described, and the possibilities and advantages of the new technology are indicated. The properties of the produced materials are discussed. Special attention is given t...
