A method of forming a string for use in a string ribbon crystal provides a refractory metal as a core for the string and forms a first layer of material on the core. A method of growing a ribbon crystal provides a pair of strings. Each string has a refractory metal core. The method further passes the strings through a molten material to grow the ribbon crystal between the pair of strings.A ribbon crystal wafer includes a ribbon crystal material and a pair of strings in the ribbon crystal material. Each string defines an outer edge of the wafer, and each string includes a refractory metal core.
