【Abstract】 The growth morphology and defects of KTiOPO₄ crystal grown by flux method are investigatedsystematically in this paper. The reasons for leading to microscopic defects such as cioudlike inclu-sion, parasites, growth striation, growth sectors and colours are analyzed and the methods for im-provement in growth process are approached. By means of optical microscope, the etch-pits on crys-tal faces are observed and the density of dislocation in different faces is counted.更多还原
