摘　　要：ε-Zn（OH）2 crystals with high thermal stability,well crystallinity and fine dispersity were prepared by aging at low temperatue from zinc nitrate and sodium hydroxide in aqueous solution. The crystal structure,morphology and thermal stability were characterized by Xray diffractometry,scanning electron microscopy and differential scanning calorimeter. The influences of reaction temperatures,mole ratios of zinc nitrate to sodium hydroxide and phase-inversion rates on the products were discussed in details.ε-Zn(OH)_2 crystals with high thermal stability,well crystallinity and fine dispersity were prepared by aging at low temperatue from zinc nitrate and sodium hydroxide in aqueous solution.
