· JVASP-9741· ThSiO4

Thorium silicate (ThSiO4) is an actinide ceramic compound that belongs to the zircon structural family, characterized by its high density and strong ionic bonding. This material is primarily of research interest in nuclear fuel cycles and advanced ceramics, where its chemical stability and radiation tolerance make it a candidate for immobilizing actinide elements and managing nuclear waste. Engineers and materials scientists study thorium silicates as potential alternatives to conventional ceramic waste forms because of their ability to incorporate radioactive elements while maintaining structural integrity under extreme conditions.
