上海钢铁研究所研制成功的高温钼坩埚,是通过粉末冶金、旋压成形方法制成的簿壁无缝、尺寸精确、组织细密的制品,可作为质谱仪的熔样坩埚。其综合性能和使用寿命与英国进口的钼坩埚相当,可在各类高温分析、熔炼等类似装置中推广应用。性能指标为:动态真空度可达:10~(?)乇;常温下,在1:1HF 中浸泡24小时未见熔蚀;再结晶温度为:1900℃;使用温度可
Shanghai Institute of Iron and Steel developed a high-temperature molybdenum crucible, which is made of powder metallurgy, spin-forming process seamless, accurate size, fine structure of the product can be used as mass spectrometer melting crucible. Its overall performance and service life comparable with the United Kingdom imported molybdenum crucible, in all kinds of high temperature analysis, melting and other similar devices in the promotion and application. Performance indicators: dynamic vacuum up to: 10 ~ (?) Torr; room temperature, immersion in 1: 1HF 24 hours without corrosion; recrystallization temperature: 1900 ℃; temperature can be
