“…The increased interest in crystalline phosphates with the Bi 4 (SiO 4 ) 3 eulytite structure is explained by the expanding prospect of their use in regenerative medicine, light-emitting diode (LED) technology, and microwave installations. − Mineral-like eulytite phases are worthy of attention in the creation of ceramic forms of nuclear waste since they contain ions of actinides, lanthanides, Sr, Rb, Cs, and phosphate ions present in the liquid highly active waste. , …”
