Abstract : Crystals grown from solution are frequently flawed by inclusions of solution that has been trapped by the crystal during the growth process. Crystals of ThO2 and ZrSiO4 were placed in a thermal gradient high enough to liquefy the inclusions. This caused the liquid to move through the crystal toward the heat source, thereby removing inclusions from the crystals. (Author)
