制備工藝的控制對(duì)鋯粉性能的影響制備工藝的控制對(duì)鋯粉性能的影響

  采用純度較高的海綿鋯,用高純氫氣深度氫化和梯度脫氫技術(shù)制備了超細(xì)鋯粉。在一定溫度下對(duì)海綿鋯進(jìn)行高純氫氣深度氫化,生成易于粉碎成細(xì)小顆粒的低氧含量氫化鋯,氫化鋯經(jīng)高能球磨后達(dá)到一定的粒度,再經(jīng)梯度式溫度下脫氫后,可得到超細(xì)鋯粉。對(duì)生產(chǎn)超細(xì)鋯粉過(guò)程中的高純氫氣深度氫化、高能球磨和梯度脫氫過(guò)程做了概要分析。結(jié)果表明,鋯中氫含量隨溫度的升高逐漸降低,在700℃時(shí)氫化鋯出現(xiàn)吸熱峰迅速分解,鋯的氫化反應(yīng)為400~700℃,脫氫反應(yīng)溫度為600~800℃。對(duì)于相同原料制取的鋯粉,氧化鋯粒度越低,其含氧量越高。
