The process comprises mixing lithium, a transition metal and a phosphorus-containing salt as starting materials, with addition of any one element selected from the group consisting of sodium (Na), potassium (K), lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), samarium (Sm), gadolinium (Gd) and erbium (Er) in an amount of less than 10 at % to thereby inhibit nucleation in a first heat treatment, subjecting the reactants to first heat treatment at a temperature of 250° C. to 400° C. for 2 to 10 hours, and subjecting the first heat-treated materials to a second heat treatment at a temperature of 400° C. to 700° C. for 2 to 24 hours to uniformly form crystalline nuclei to induce growth of nanocrystalline particles.

摘要： The invention relates to a method for growing single crystals of barium titanate [BaTiO3] and barium titanate solid solutions [(BaxM1−x)(TiyN1−y)O3]. This invention is directed to a method for growing single crystals of barium titanate or barium titanate solid solutions showing the primary and secondary abnormal grain growths with increasing temperature higher than the liquid formation temperature, characterized by comprising the step for a few secondary abnormal grains to continue to grow at a temperature slightly below the critical temperature where the secondary abnormal grain growth starts to occur. The method for growing single crystals of barium titanate or barium titanate solid solutions according to this invention has the advantage of providing an effective low cost in manufacturing process for single crystals by using a conventional heat-treatment process without the need of special equipment. The method for growing single crystals of barium titanate and barium titanate solid solutions according to this invention is also applicable to other material systems showing abnormal grain growth behavior.
