Chii chinonzi Boron Carbide B4C?

Boron carbide, inozivikanwawo sedhaimani dema, chinhu chisina kugadzirwa chine kemikari formula B4C. Kirista yakasviba yakasviba inopenya.

Iine kuomarara kweMohs ingangoita 9.5, zvichiita kuti ive imwe yezvinhu zvitatu zvakaomesesa zvinozivikanwa (mushure medhaimondi uye cubic boron nitride). Haina kusimba pane zvakawanda zvehari. Inoshandiswa mu tank armor, bullet-proof vests uye akawanda maindasitiri ekushandisa. Relative density (D204) 2.508 kusvika 2.512. Melting point i2350 ℃. Iyo yekubikira nzvimbo ye3500 ℃.

Boron carbide haina kuita ne acid uye alkali solution, ine high chemical potential, haina kuita ne acid uye alkali solution, ine high chemical potential, neutron absorption, kupfeka resistance uye semiconductor conductivity. Ndiyo imwe yeakanyanya kugadzikana kune acids uye yakagadzikana mune zvese concentrated kana dilute acid kana alkaline mhinduro. Boron carbide inonyanya kugadzikana pasi pe800 ℃ munzvimbo yemhepo, nekuda kwekushisa kwepamusoro kwe oxidation ye boron oxide mukurasikirwa kwegasi, zvichikonzera kusagadzikana kwayo, oxidation kuumba carbon dioxide uye boron trioxide.

Yakawanikwa muzana ramakore rechi 19 sechigadzirwa chetsvakiridzo pasimbi borides uye haina kudzidzwa nesainzi kusvika kuma1930. Boron carbide inogona kugadzirwa nekudzikisa boron trioxide nekabhoni muchoto chemagetsi.

Nemhaka yehushoma hwayo, simba guru, kugadzikana kwekushisa kwepamusoro uye kugadzikana kwakanaka kwemakemikari. Mukupfeka zvinodzivirira zvinhu, ceramic kusimbisa, kunyanya muchiedza chezvombo, reactor neutron absorbent applications. Mukuwedzera, kana ichienzaniswa nedhaimondi uye cubic boron nitride, boron carbide iri nyore kugadzira, mutengo wakaderera, saka inoshandiswa zvakanyanya, mune dzimwe nzvimbo inogona kutsiva dhaimondi rinodhura, rinowanikwa mukukuya, kugaya, kuchera uye mamwe maapplication.

Chii chinonzi Boron Carbide B4C Inoshandiswa?

Kudzora kuparara kwenyukireya

Boron carbide inokwanisa kutora manyuturoni akawanda pasina kuumba chero isotopi ine radioactive, zvichiita kuti ive yakanakira kunyuturu yemagetsi enyukireya, uko manyuturoni anonwisa anodzora mwero wenyukireya fission. Boron carbide inonyanya kushandiswa mumagetsi enyukireya setsvimbo inodzoreka, asi dzimwe nguva inogadzirwa kuva poda kuwedzera nzvimbo.

Panjodzi yenyukireya yeChernobyl muna 1986, Russia yakazomisa kuita kwecheni mureactor mushure mekudonhedza matani zviuru zviviri zveboron carbide nejecha.

Abrasive zvinhu

Boron carbide yakashandiswa seyakakora abrasive zvinhu kwenguva yakareba. Nekuda kwekunyanya kunyungudika kwayo, hazvisi nyore kukanda muzvigadzirwa, asi nekunyungudutsa hupfu pakupisa kwakanyanya, inogona kugadzirwa kuita maumbirwo ari nyore. Inoshandiswa kukuya, kukuya, kuchera nekukwenenzvera zvinhu zvakaoma senge hard alloy nedombo rinokosha.

Coating pendi

Boron carbide inogona zvakare kushandiswa seyakavakirwa ceramic yezvikepe zvehondo uye zvikopokopo. Ikareruka uye inokwanisa kuramba mabara anobaya nhumbi dzokurwa achipinda mubhachi rinodzvanywa rinopisa rose.

kamwene

Inoshandiswa muindasitiri yezvombo kugadzira pfuti dzepfuti. Boron carbide, yakanyanya kuoma uye isingapfekere, haina kuita neasidhi uye alkali, yakakwirira/yakaderera tembiricha kuramba, kukwirira kudzvinyirira, density ≥2.46g/cm3; Microhardness ≥ 3500kGF / mm2, kukotama simba ≥400MPa, kunyunguduka ndiko 2450 ℃.

Nekuti boron carbide nozzle ine hunhu hwekupfeka kuramba uye kuoma kwakanyanya, boron carbide sandblasting nozzle zvishoma nezvishoma inotsiva inozivikanwa carbide/tungsten simbi uye silicon carbide, silicon nitride, alumina, zirconia uye zvimwe zvinhu zvejecha rinoputika.

vamwe

Boron carbide inoshandiswawo mukugadzirwa kwesimbi borides uye kunyungudutswa kwe sodium boron, boron alloys uye yakakosha welding.
