Hafnium Flat Product 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 yog qhov nyuaj rau kev cais cov zirconium, vim tias ob lub ntsiab lus muaj cov atoms uas loj tib yam.
Cov ntawv thov Hafnium suav nrog cov tshuab hluav taws xob nuclear, nuclear submarines, cov cuab yeej kho mob, roj hlwb, hnub ci zog.
