Abstract
This project aims to obtain garnets containing rare earth ions (Ce³¿ and Gd³¿) through the controlled precipitation of the desired crystalline phase, using special glass compositions as a reaction medium. Glasses with the composition GeO¿-PbO-Bi¿O¿-Ga¿O¿-TR¿O¿ (where TR = Ce¿O¿ or Gd¿O¿) are melted at temperatures close to 1200°C. After complete homogenization, controlled cooling is carri…
