Abstract
Material of Na,0 doped 12Ca07Al203 (C 12A7-Na20) was prepared by the sol-gel method. And the precursor was sintered at 1623K for 3h. The phase composition and crystal structure of C12A7-Na20 was investigated by XRD analysis. The results indicated that Na20 would occupy the position of CaO or vacancy of C12A7 lattice and promote the formation of C12A7 when calcium/aluminum ratio (Ca0/Al203, molar ratio) was 1.4. Na20 would promote the formation of C3A when calcium/aluminum ratio was 1.7. The lattice parameters also proved the solid solution between C 12A7 and Na20. Alumina leaching experiments were carried out in sodium carbonate solution and the relationship between leaching ratio and doping content, calcium/aluminum ratio were established.
