He aha ka Boron Carbide B4C?

ʻO Boron carbide (B4C) he mea paʻakikī loa ka boron-carbon ceramic a me nā mea covalent i hoʻohana ʻia i loko o nā mea kaua pahu, nā ʻaʻahu pale pōkā, ka pauka pōʻino mīkini, a me nā noi ʻoihana he nui. ʻOi aku ka paʻakikī o Vickers ma mua o 30GPa, ʻo ia kekahi o nā mea paʻakikī i ʻike ʻia, ʻelua wale nō i ka CBN a me ke daimana. 

Manaʻo ʻia ʻo Boron carbide he mea paʻa me ka paʻakikī kiʻekiʻe loa (ka pālākiō Mohs ma kahi o 9.5 a 9.75), nā ʻāpana hoʻoheheʻe neutron kiʻekiʻe (ʻo ia hoʻi ka pale maikaʻi i nā neutrons), a me ka paʻa i ka radiation ionizing a me ka hapa nui o nā kemika. ʻO kona paʻakikī Vickers (38GPa), modulus elastic (460GPa), a me ka paʻakikī haʻihaʻi (3.5MPa·m(1/2)) kokoke i nā daimana (1150GPa a me 5.3MPa·m(1/2)). 

I ka makahiki 2015, ʻo ka boron carbide ke kolu o ka mea paʻakikī loa i ʻike ʻia, ma hope o ke daimana a me ka cubic boron nitride, a loaʻa iā ia ka inoa i kapa ʻia ʻo "black diamond".

ʻO Boron carbide kahi semiconductor nona nā waiwai uila e hoʻokele nui nei i ka halihali. Aia nā āwaha i ka haku mele a me ka pae o ka hoʻonohonoho. Manaʻo ʻia ka 2.09 eV, a he nui nā mokuʻāina waena waena e paʻakikī i ka spectrum photoluminescence. ʻO ka mea maʻamau ka p-type. 

He aha ka Boron Carbide i hoʻohana ʻia no? 

Hoʻohana ʻia ʻo Boron carbide i nā refractory ma muli o kona kiʻekiʻe heheʻe a me ka paʻa wela; Ma muli o kona kūpaʻa ikaika loa, hoʻohana ʻia ia e like me ka pauka wili a me ka uhi; ʻO ka paʻakikī kiʻekiʻe, haʻahaʻa haʻahaʻa, a me ka hana ballistic maikaʻi loa; Hoʻohana maʻamau ia ma ke ʻano he neutron radiation absorber i nā noi nuklea. Eia kekahi, ʻo ka boron carbide he semiconductor wela kiʻekiʻe e hiki ke hoʻohana ʻia no nā noi uila hou.

Hiki ke hoʻohana ʻia ka boron carbide e like me: 

ʻO ka padlock 

ʻO ka pahu pale no ka pilikino a me ke kaʻa 

Nozzle sandblasting 

ʻO ka nozzle ʻoki ʻoki wai kiʻekiʻe 

ʻO ka uhi paʻa ʻole a me ka ʻaʻahu 

ʻOki ʻoki a make 

hoʻopau 

Metala matrix composites 

I ke kaʻa kaʻa 

Neutron absorber i loko o ka nuclear reactor 

Kiʻekiʻe ikehu wahie no paʻa wahie ramjets 

ʻO Boron Carbide ka paʻakikī loa? 

ʻO Boron carbide ka Mohs paʻakikī ma waena o 9 a me 10 a ʻo ia kekahi o nā mea synthetic paʻakikī i ʻike ʻia, ʻelua wale nō i ka cubic boron nitride a me ke daimana. 

Hiki iā Boron Carbide ke ʻoki i ke daimana? 

Ma muli o kona paʻakikī kiʻekiʻe, hoʻohana ʻia ka pauka boron carbide ma ke ʻano he abrasive i ka polishing a me ka wili ʻana i nā noi a me ke ʻano abrasive hoʻokuʻu i ka ʻoki ʻana i nā noi e like me ka ʻoki ʻana i ka wai. Hiki ke hoʻohana ʻia no ka ʻaʻahu ʻana i nā mea hana daimana.

Kumukuai Boron Carbide B4C

Hoʻopili ʻia ke kumukūʻai e nā kumu he nui e like me ka hoʻolako a me ka noi ma ka mākeke, nā ʻano ʻoihana, nā hana waiwai, nā manaʻo mākeke, a me nā hanana i manaʻo ʻole ʻia.

Inā ʻoe e ʻimi nei i ke kumukūʻai B4C hou loa, hiki iā ʻoe ke hoʻouna mai iā mākou i kāu nīnau no kahi ʻōlelo kūʻai. ( [email protected] )

Mea kūʻai mai Boron Carbide B4C

ʻO RBOSCHCO kahi mea kūʻai aku a me nā mea hana mea hoʻohana i ʻoi aku ma mua o 12 mau makahiki i ka hāʻawi ʻana i nā kemika kiʻekiʻe kiʻekiʻe a me nā nanomaterials. Hoʻokuʻu aku ka hui i nā ʻāina he nui e like me USA, Canada, Europe, UAE, South Africa, Tanzania, Kenya, Egypt, Nigeria, Cameroon, Uganda, Turkey, Mexico, Azerbaijan, Belgium, Cyprus, Czech Republic, Brazil, Chile, Dubai, Iapana, Korea, Vietnam, Thailand, Malaysia, Indonesia, Australia, Kelemānia, Palani, Italia, Pokukala, etc.

Ma ke ʻano he mea hana hoʻomohala nanotechnology alakaʻi, ʻo RBOSCHCO ka luna o ka mākeke. Hāʻawi kā mākou hui hana ʻoihana i nā hāʻina kūpono e kōkua i ka hoʻomaikaʻi ʻana i ka pono o nā ʻoihana like ʻole, hana i ka waiwai, a maʻalahi hoʻi i nā pilikia like ʻole.

Inā ʻoe e ʻimi nei iā B4C, e ʻoluʻolu e leka uila. ( [email protected] )
