ʻO ka Boron carbide (ke kumu hoʻohālikelike e pili ana i ka B4C) he mea ʻoi loa a paʻakikī i hana ʻia e ke kanaka i hoʻohana ʻia ma ke ʻano he abrasive a refractory a me nā koʻokoʻo mana i nā reactors nuklea, kani ultrasonic drilling, metallurgy a me ka nui o nā noi ʻoihana. ʻO ia kekahi o nā mea paʻakikī loa i ʻike ʻia, ma hope o cubic boron nitride a me daimana. ʻO kāna mau waiwai koʻikoʻi ka hardness.corrosion kū'ē i nā kinikini reactive, ikaika wela maikaʻi loa, haʻahaʻa haʻahaʻa kikoʻī a me ka modulus elastic kiʻekiʻe.

E HOAKAKA ANO

Nā noi

Ua kūpono ʻo Boron Carbide i nā ʻano hana ʻoihana like ʻole:

Abrasives no ka lapping a me ka ultrasonic cutting, Anti-oxidant i carbon-bonded refractory mixes, Armor Nuclear applications e like me ka reactor control rods a me ka neutron absorbing shielding.

E hoʻohana i nā ʻāpana e like me nā nozzles pahū, nā make huki uea, nā metala pauka a me nā mea hana seramika, nā alakaʻi pae.

Hoʻohana ʻia ia ma ke ʻano he mea hoʻohui i nā refractory hoʻolei hoʻomau ma muli o kona kiʻekiʻe metling point a me ka thermal stability.

Kaʻina Hana Hana

Hoʻoheʻe ʻia ʻo Boron Carbide mai ka boric acid a me ka pauka kalapona i loko o ka umu uila ma lalo o ka wela kiʻekiʻe. ʻO ia kekahi o nā mea paʻakikī i hana ʻia e ke kanaka i loaʻa i nā mea kūʻai aku me ka palena haʻahaʻa e hiki ai ke hana maʻalahi i nā ʻano. ʻO kekahi o nā waiwai kūʻokoʻa o Boron Carbide: ʻo ka paʻakikī kiʻekiʻe, ka inertness kemika, a me ka neutron kiʻekiʻe e hoʻopaʻa ʻia, pauku kea.
