制備工藝的控制對鋯粉性能的影響制備工藝的控制對鋯粉性能的影響

  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。對生產(chǎn)超細(xì)鋯粉過程中的高純氫氣深度氫化、高能球磨和梯度脫氫過程做了概要分析。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℃。對于相同原料制取的鋯粉,氧化鋯粒度越低,其含氧量越高。
