Quenching Glass Ceramic

For different concentrations the emission spectra and decay curves of the 4i13 2 4i15 2 emission were measured.

Quenching glass ceramic.

Do micro structural properties after different rate of quenching simultaneously measure the physical properties also. Glass ceramics with nanocrystals present a transparency higher than that expected from the theory of rayleigh scattering. In this paper phosphate based glass ceramic waste forms containing monazite cepo 4 as crystalline phase were prepared by a melt quenching process using nh 4 h 2 po 4 h 3 bo 3 fe 2 o 3 and ceo 2 as the feed materials and the formation process was analyzed.

Quenching effect will be there on both physical and structural properties. The er concentration dependence of integrated intensity and lifetime of 4i13 2 4i15 2 emission are showed. This ultratransparency is attributed to the spatial correlation of the nanoparticles. Glass ceramics are polycrystalline materials produced through controlled crystallization of base glass.

Monazite iron phosphate glass ceramic wasteforms were prepared by a melt quenching process. The thermal quenching of fluorescence of ce y 3 al 5 o 12 glass ceramic yag gc phosphor was evaluated and compared with those of ce y 3 al 5 o 12 polycrystal yag pc and ce gd y 3 al 5 o 12 glass ceramic gdyag. With the increase of the er3 doping. Ce la nd po 4 phosphate based glass ceramics are potential candidates for the hlw.

The glass reagents high purity powders of sio 2 ca 3 po 4 2 caco 3 mgco 3 4 mg oh 2 5h 2 o na 2 co 3 and k 2 co 3 1. The glass referenced as cel2 was prepared by a traditional melting quenching process. The feasibility to immobilize the hlw by monazite iron phosphate glass ceramics is discussed.
