摘要: The influence of fluorite content the glass on formation and properties polyalkenoate cements was investigated. A series powders based 1.5SiO2·0.5P2O5·Al2O3·CaO·XCaF2 were synthesised. transition temperature fell with increasing content. Setting working times cement pastes decreased glass. Compressive strength un-notched fracture increased Fracture toughness relatively insensitive to
