  • Method for large scale synthesis of optically stimulated luminescence grade polycrystalline ceramic material
    Patent number: 9523033
    Abstract: A method for the synthesis of OSL grade polycrystalline mass of ceramic materials with dopant C involving source ceramic material preferably in its readily available powder form comprising the steps of melting of the said ceramic material in graphite environment including a graphite crucible/container in vacuum; and obtaining there from polycrystalline aggregate by rapid solidification of said melt to thereby provide said polycrystalline mass of ceramic materials with dopant C of optically stimulated luminescence grade. The said powder form of the ceramic material is compacted and formed into pellets before subjecting to melting.
    Type: Grant
    Filed: June 24, 2013
    Date of Patent: December 20, 2016
    Assignee: THE SECRETARY, DEPARTMENT OF ATOMIC ENERGY
