Abstract:
This patent application discloses an invention related to the area of glass processing. Defect-free fluoride glass materials are made by hot isostatic pressing HIP of a fluoride glass. The process may be used to manufacture preforms or bulk fluoride glass. The external pressure applied during HIP squeezes bubbles from the glass and permits the use of a wider range of working temperatures than ordinarily available, thereby reducing crystallization defects.
