刚玉坩埚

本文研究了用作铂金坩埚代用品的纯刚玉坩埚。分析了纯刚玉的结构，测试了纯刚玉坩埚的性能，并对影响纯刚玉坩埚性能的因素进行了探讨。

The paper studies the pure corundum crucible which replaces platinum crucible , analyzed the structure of the pure corundum , tested its properties and discussed the factors which influence the properties of the pure corundum crucible .

采用NaCl和Na2CO3作复合助熔剂，结合回熔、坩埚套装方法，在高纯氧化铝刚玉坩埚中生长出毫米大小的常温反铁电体NaNbO3晶体；

NaNbO_3 crystals , several millimeters large in size , have been grown successfully in corundum crucible with high purity , which is attributed to a combination of composite fluxes of NaCl and Na_2CO_3 , melt-back process and imbedded crucibles .

纯刚玉代铂坩埚的研制

A Study on the Replacement of Platinum Crucible by Pure Corundum Crucible

与铂、银、镍、刚玉、石英等坩埚比较，具有引入杂质少成本低等优点。

And excels the platinum , silver , nickel , corundum , and quartz at a lower cost and less contamination .
