reacting weight
1.When the reaction conditions were reacting temperature of 30-55 ℃, In3+ concentration<150 g/L, sodium hydroxide concentration < 250 g/L,and pH value of 10-11.5, experimental results show that CIO powder has cubic structure, well distribution, finer dispersing in matrix, CuO:In2O3 (weight) =70:30, the mean grain size is about 27.815 nm and specific area 42.06 m2/g.
2.A novel dimethacrylates monomer,9,9′-bis(4-hydroxy-phenyl) fluorenyl diglycidyl methacrylate(HPFDM) with molecular weight is 634, was prepared by epoxying 9,9′-bis(4-hydroxy-phenyl) fluoenyl(9′9-HPF) with epoxy chloropropane,and then further reacting with methacrylic acid. The resinbased root canal sealer(NRCS) was made of this novel monomer as one of chief component.
