Abstract
A method of pulling a crystal of a metal oxide is disclosed, in which the growth of the crystal is performed in a liquid phase having a composition which is different from the metal oxide and which contains components constituting the metal oxide. The liquid phase is in contact with a solid phase located at a position separated from the position at which the crystal of the metal oxide grows. The solid phase has a composition different from that of the metal oxide and supplies components constituting the metal oxide to the liquid phase.
