中文摘要:

      以尿素分解产生的NH3为沉淀剂,通过分阶段控制温度直接在水热反应釜均匀沉淀薄片状氢氧化镁。电镜扫描示粒子呈棱形形状,粒度分布均匀、晶形好、纯度高。

英文摘要:

      Lamellar Magnesium hydroxide was synthesized by a homogeneous precipitation method,with direct reaction in the autoclave. It utilized ammonia as the precipitator produced by urea hydrolysis. The particle shape was controlled by the grading reaction temperature. Scanning electron micrographs revealed that the products were uniform, well-defined, rather pure prism particles.
