B4C nanopowder Boron carbide bubuk kanggo bahan welding
Deskripsi Produk
Boron carbide minangka zat anorganik, biasane bubuk abu-abu-ireng.Kapadhetan dhuwur (2,55g/cm³), titik leleh dhuwur (2350 ° C), lan stabilitas kimia sing apik lan panyerepan neutron.Bahan kasebut atos banget, padha karo kekerasan berlian, lan nduweni sifat penyerap neutron.Iki nyebabake panggunaan boron karbida ing pirang-pirang lapangan, kayata energi nuklir minangka penyerap neutron, uga bahan tahan aus, fase penguatan keramik, waja entheng, lan utamane penyerap neutron reaktor nuklir.
