B4C nanopowder Boron carbudi poda kwa ajili ya vifaa vya kulehemu
Maelezo ya bidhaa
Boroni carbudi ni dutu isiyo ya kawaida, kwa kawaida poda ya kijivu-nyeusi.Ina msongamano mkubwa (2.55g/cm³), kiwango cha juu myeyuko (2350 ° C), na uthabiti bora wa kemikali na ufyonzaji wa nyutroni.Nyenzo ni ngumu sana, sawa na ugumu wa almasi, na ina mali ya kunyonya neutron.Hii imesababisha matumizi ya CARBIDI ya boroni katika nyanja nyingi, kama vile nishati ya nyuklia kama kifyonza cha nyutroni, na vile vile vifaa vinavyostahimili uvaaji, awamu ya uimarishaji wa kauri, silaha nyepesi, na kinyonyaji cha nutroni cha nyuklia.
