Transparent Beryllia Ceramics for Laser Technology and Ionizing Radiation Dosimetry

Transparent Beryllia Ceramics for Laser Technology and Ionizing Radiation Dosimetry A technology for preparation of transparent beryllia ceramics has been developed using Li2CO3 as a modifier at relatively low temperatures (not above 1570 K) and moderate molding pressures (up to 40.0 MPa). Optimum pressure molding time, average grain size, and dopant concentrations (Li2CO3 + rare-earth oxides) to increase luminescence intensity are specified. The transparent dense BeO ceramic may be of interest for laser technology (especially in the middle infrared) as material for fabrication of dielectric resonant tubes, waveguides, and dielectric nontransmitting mirrors. The transparent BeO ceramic is a promising material for developing a new generation of tissue-equivalent scintillators for the dosimetry of ionizing radiation. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Refractories and Industrial Ceramics Springer Journals

Abstract

A technology for preparation of transparent beryllia ceramics has been developed using Li2CO3 as a modifier at relatively low temperatures (not above 1570 K) and moderate molding pressures (up to 40.0 MPa). Optimum pressure molding time, average grain size, and dopant concentrations (Li2CO3 + rare-earth oxides) to increase luminescence intensity are specified. The transparent dense BeO ceramic may be of interest for laser technology (especially in the middle infrared) as material for fabrication of dielectric resonant tubes, waveguides, and dielectric nontransmitting mirrors. The transparent BeO ceramic is a promising material for developing a new generation of tissue-equivalent scintillators for the dosimetry of ionizing radiation.
