日本东芝公司研制出一种用于熔炼稀土金属的高强、高抗腐蚀性的坩埚材料——含氧化钇的钨合金。据称,钨和陶瓷颗粒如Y2O3结合可提高合金的强度和抗腐蚀性,与普通含钽的坩埚材料相比,其使用寿命提高了10倍(使用寿命取决于抗腐蚀性);抗弯强度达到800MPa(1000℃时),超过纯钨坩埚的
Toshiba Japan has developed a high-strength, high corrosion-resistant crucible material for the melting of rare earth metals - yttrium oxide-containing tungsten alloy. Allegedly, tungsten and ceramic particles such as Y2O3 combination can improve the strength and corrosion resistance of the alloy, compared with the ordinary tantalum containing crucible material, the service life of 10 times (service life depends on corrosion resistance); flexural strength Reached 800MPa (1000 ℃), more than pure tungsten crucible
