The influence of uniform vibration on the stability of crystallization front in prizmatical ampule under microgravitation conditions is considered. The vertical and horizontal vibrations are studied. It is established that horizontal vibration causes curving of the crystallization front, which results in a worsening of crystal quality. Vertical vibration induces agitation of melt and, under certain conditions, may improve crystal characteristics
