The crystallographic texture of a zone melted Bi2Sr2Ca1Cu2Oy high temperature superconductor was studied by X-ray diffraction technique. Semi-quatitative methods were suggested for texture estimation in this material. Some texture parameters were revealed to describe the texture state of the samples and to define their superconducting transport properties. A mechanism of the texture formation under zone melting treatment of the samples and some features of the texture were discussed.
