Tlhaloso e Khutšoane

Boron carbide (chemical formula almost B4C) is an extremel y hard man-mad material e sebelisoang e le abrasive and refractory and in control rods in nuclear reactors, ultrasonic drilling, metallurgy and num erous industrial applications.With a Mohs hardness of about 9.497, it ke e 'ngoe ea lisebelisoa tse thata ka ho fetisisa tse tsejoang, ka morao ho cubic boron nitride le diamond. Litšobotsi tsa eona tse hlahelletseng ke ho thatafala ho feteletseng.ho hanyetsana le lik'hemik'hale tse ngata tse sebetsang, matla a chesang haholo, matla a khoheli a tlase haholo le modulus e phahameng ea elastic.

Mokhoa oa Tlhahiso

Boron Carbide e qhibilihisoa ho tloha boric acid le carbon powder ka seboping sa motlakase tlas'a mocheso o phahameng. Ke e 'ngoe ea lisebelisuoa tse thata ka ho fetisisa tse entsoeng ke motho tse fumanehang ka bongata ba khoebo tse nang le ntlha e lekanyelitsoeng ea ho qhibiliha e tlaase ho lekana ho lumella ho etsoa ha eona habonolo hore e be libopeho. Tse ling tsa thepa e ikhethang ea Boron Carbide li kenyelletsa: boima bo phahameng, ho se sebetse ha lik'hemik'hale, le ho monya neutron e phahameng, karolo ea sefapano.
