and then decreases slightly. It is appropriate that the Ni and Al ions concentration and the ratio of urea to Ni and Al ions are 0.42mol/L and 0.75∶1, respectively. Key words: homogeneous precipitation method; α-Ni... step and the sample particle prepared by this method is large and its electrochemical performance is poor. For homogeneous precipitation, by controlling the concentration of reagents, the precipitation......
Preparation and Characteristics of Hydroxyapatite Whiskers by Homogeneous Precipitation Method王友法摘 要:Hydroxyapatite whiskers were prepared by the homogeneous precipitation method. Soluble calcium ion and phosphate ion were used as initial materials, they were refluxed respectively at 85℃ , 90℃ and 95℃ for various lengths of time. A proper precipitation......
