二步还原温度对铼粉物理性能的影响
Optimization of Two-Step Reduction Temperature on Physical Properties of Rhenium Powders
摘要
Abstract
Rhenium powder is an important doping raw material in the aerospace and nuclear industries.Its exceptional physical properties are prerequisite for its application.This study utilized high-purity ammonium rhenate from Guixi Smelter of Jiangxi Copper Corporation Limited as raw material,and devised a gradient of six two-step reduction temperatures.By employing equipment such as field emission scanning electron microscopy(FESEM),powder comprehensive characteristic analyzer,laser particle size analyzer,Fisher particle size analyzer,and oxygen-nitrogen-hydrogen analyzer,we comprehensively assessed the effects of reduction temperatures on the physical properties of rhenium powders.The research results indicated that when the two-step reduction temperature fell within the range of 800℃to 900℃,rhenium powder exhibited superior physical properties,achieving a compact density over 10 g/cm3.Besides,the oxygen content satisfied the specifications stipulated in the superior Re standard of YS/T 1017-2015.关键词
