GLASS-CERAMICS IN LEAD FLUOROBORATE AND FLUOROSILICATE SYSTEMS CODOPED La/Nd
Properties and controlled crystallization of lead fluoroborate and fluorosilicate glasses, co-activated by lanthanum and neodymium fluorides, were studied. It is established that an increase in the concentration of rare-earth metals contributes to the stabilization of the cubic phase of a solid solution based on lead fluoride with an effective occurrence of neodymium into the crystalline phase.
