A nanosized zirconia precursor powder has been synthesized via an inverse microemulsion processing route, in which 53 wt% cyclohexane was used as the oil phase and 35 wt% mixed poly (oxyethylene) 5 nonyl phenol ether (NP5) and poly (oxyethylene) 9 nonyl phenol ether (NP9) were used as the mixed nonionic surfactant (weight ratio 1:1). Two microemulsion systems were prepared, containing...
A submicrometer-sized hydroxyapatite powder has been synthesized via an inverse microemulsion processing route, which uses cyclohexane as the oil phase, mixed poly(oxyethylene) 5 nonyl phenol ether (NP-5) and poly(oxyethylene) 9 nonyl phenol ether (NP-9) as the surfactant phase, and an aqueous CaCl 2 solution as the water phase. In comparison with the hydroxyapatite powder...
