Hafnium Sponge Description
Hafnium muaj qhov zoo corrosion kuj thiab siab zog. Nws tiv taus corrosion vim tsim cov tawv tawv, impenetrable oxide zaj duab xis ntawm nws qhov chaw. Hafnium tsis cuam tshuam los ntawm alkalis thiab acids, tsuas yog hydrofluoric acid.
Hafnium daim txhuam cev yog lub siab purity, coarse hmoov, los yog granular daim ntawv ntawm hafnium hlau nrog siab porosity. Hafnium hlau daim txhuam cev feem ntau yog 3-25mm (lwm qhov ntau thiab tsawg yuav muaj los ntawm kev thov) thiab muaj ntau yam kev siv suav nrog kev ua haujlwm raws li cov pa oxygen getter thiab catalyst. Hafnium sponge tseem tuaj yeem siv rau hauv kev lag luam atomic zog, kev lag luam aerospace, thiab kev lag luam foob pob hluav taws.
