Chii chinonzi titanium diboride chinangwa?

Titanium diboride chinangwa inogadzirwa ne titanium diboride. Titanium diboride igrey kana greyish dema ine hexagonal (AlB2) crystal chimiro, inonyungudika inosvika 2980 ° C, density ye4.52g/cm³, uye microhardness ye34Gpa, saka ine yakanyanya kuoma.ess. Iine oxidation kuramba tembiricha inosvika 1000 ℃ mumhepo, uye inoramba yakatsiga muHCl neHF acids, ichiratidza kugwinya kweasidhi kuonda.Zvinhu zvezvinhu zvinotevera: coefficient yekuwedzera kwekushisa: 8.1 × 10-6m / m · k; Thermal conductivity: 25J/m·s·k; Kuramba: 14.4μΩ · cm;

Ichi chinyorwa chinewo chakanaka chekupisa uye chemagetsi conductivity, saka chinoshandiswa zvakanyanya munzvimbo dzakasiyana siyana dzeindasitiri, senge vacuum coating, ceramic yekucheka maturusi uye mold, yakakwirira tembiricha crucible, injini zvikamu uye zvichingodaro. Panguva imwecheteyo, chinangwa chetitanium diboride ndichowo chinangwa chakakosha chekugadzirira titanium alloys, high hardness ceramics uye kusimbiswa kwekongiri.

 Nzira yekugadzira chinangwa chetitanium diboride?

1.Direct synthesis method: Iyi nzira ndeyekubatanidza zvakananga titanium uye boron powder mune yakakwirira-temperature reactor kuti ibudise titanium diboride. Nekudaro, iyo tembiricha yekuita iyi nzira inofanirwa kunge iri pamusoro pe2000℃, mutengo wezvinhu zvakasvibirira wakakwira, nzira yacho haisi nyore kudzora, mhinduro haina kukwana, iyo yakagadzirwa TiB2 yakaderera mukuchena, uye iri nyore kugadzira TiB, Ti2B uye mamwe makomisheni.

2.Borothermal nzira: Iyi nzira inoshandisa TiO2 (kuchena kwakakwira kupfuura 99%, chimiro chease, particle size 0.2-0.3μm) uye amorphous B (kuchena 92%, particle size 0.2-0.3μm) seyakagadzirwa, kuburikidza nereshiyo chaiyo uye bhora kugaya maitiro (kazhinji anoitwa pasi pevacuum), pakuita tembiricha isingapfuuri 1100 ° C kugadzirira titanium. diboride.

3. Nyusa electrolysis: Munzira iyi, titanium oxides inopindirana nealkali (kana alkaline pasi) metal borates uye fluorates pasi pemamiriro ekunyunguduka kwe electrolysis kuti iite titanium dib.oride.
Imwe neimwe yeaya maitiro ekugadzira ane hunhu hwayo, iyo chaiyo sarudzo yeiyi maitiro zvinoenderana nezvinodiwa zvekugadzira, mamiriro emidziyo uye mutengo wehupfumi nezvimwe zvinhu.

Ndeapi minda yekushandisa yeThe titanium diboride chinangwa?

Iwo makuru ekushandisa nzvimbo dzetitanium diboride zvinangwa zvakakura kwazvo, kunyanya kusanganisira zvinotevera zvinhu:

Kudzoreredza simba uye kuchengetedza simba: Titanium diboride inogona zvakare kushandiswa kugadzira thermoelectric zvinhu zvinoshandura kupisa simba kuita magetsi.
Pamusoro pezvo, zvibodzwa zvetitanium diboride zvinoshandiswa zvakanyanya mumotokari, zvemagetsi, simba idzva, masekete akabatanidzwa, kuchengetedza ruzivo uye mamwe maindasitiri.

Yakawanda sei iyo titanium diboride chinangwa?

Mutengo wetitanium diboride tarisiro inosiyana zvichienderana nerudzi, kuchena, saizi, saizi yechikamu, kurongedzerwa kutsanangurwa uye zvimwe zvinhu.Zvinoenderana nekotesheni yevamwe vatengesi, mutengo unogona kubva pamakumi kusvika kuzviuru zveyuan. Semuyenzaniso, mutengo weimwe titanium diboride zvinangwa i85 yuan, 10 yuan (yekuedza tsvakiridzo yesainzi), 285 yuan (granular) 2000 yuan tarisiro kana kupfuura (yakanyanya kuchena, magnetron sputtering). Izvo zvinofanirwa kucherechedzwa kuti iyi mitengo inongori mareferenzi, mutengo chaiwo unogona kuchinja nekuda kwekupihwa kwemusika uye kudiwa, kushanduka kwemitengo yezvinhu uye zvimwe zvinhu.

Maitiro ekusarudza iyo yepamusoro mhando yetitanium diboride chinangwa?

1.Kuonekwa uye ruvara: Zvinangwa zveTitanium diboride zvinowanzova grey kana grey-dema, uye chitarisiko chinofanira kuva yunifomu pasina tsvina yakajeka kana mavara emavara. Kana ruvara rwakanyanya kusviba kana chiedza, kana kuti pane kusvibiswa pamusoro pepamusoro, zvinogona kuratidza kuti kuchena kwayo hakusi kwepamusoro kana kune dambudziko mukugadzirira.
2.Kuchena: Kuchena indekisi yakakosha yekuyera kunaka kwetitanium diboride chinangwa. Iyo yakakwirira kuchena, iyo yakanyanya kugadzikana kuita kwayo uye kushomeka kwemukati. Kuchena kwechinangwa kunogona kuyedzwa nekuongororwa kwemakemikari nedzimwe nzira kuti ive nechokwadi chekuti inosangana nezvinodiwa zvekushandisa.
3.Density uye kuoma: Titanium diboride ine yakakwira density uye kuomarara, iri zvakare yakakosha embodiment yekuita kwayo kwakanakisa. Nekuyera kuwanda uye kuomarara kwechinhu chakanangwa, kunaka kwayo kunogona kutongwa kwekutanga. Kana kuwanda uye kuoma zvisingasviki zviyero, zvinogona kuratidza kuti pane dambudziko negadziriro yekugadzirira kana zvinhu zvakasvibirira.
4.Electrical and thermal conductivity: Titanium diboride ine yakanaka magetsi uye yekupisa conductivity, chiri chikonzero chakakosha chekushandiswa kwayo kwakakura mumunda wemagetsi uye simba. Iyo yemagetsi uye yekupisa conductivity yechinangwa inogona kuongororwa nekuyera resistivity uye kupisa kwekushisa kwechinangwa.
5.Kemikari yekuumbwa kwekuongorora: Kuburikidza nemakemikari ekuumbwa kwekuongorora, zvirimo uye chikamu chezvinhu zvakasiyana muchinangwa chinogona kunzwisiswa, kuitira kuti uone kana ichisangana nechiyero. Kana zvinyorwa zvezvinhu zvisina kuchena muchinangwa zvakanyanyisa, kana chikamu chezvinhu zvikuru zvisingasviki zvinodiwa, zvinogona kuratidza kuti hutano hwayo husina kunaka.
Kugadzirira: Kunzwisisa maitiro ekugadzirira kwechinangwa kunogona kubatsirawo kutonga kunaka kwayo. Kana iyo nzira yekugadzirira yakakwira uye kutonga kwacho kwakasimba, izvo zvinonangwa zvinhu zvine mhando iri nani zvinowanzo kuwanikwa. Pane zvinopesana, kana nzira yekugadzirira iri kumashure kana kusadzorwa zvakanaka, kunaka kwechinangwa kunogona kunge kusina kugadzikana kana kukanganisa.
6.Mukurumbira wemupi: Kusarudza mutengesi ane mukurumbira zvakare chikamu chakakosha chekuona kunaka kwezvinhu zvinotarirwa. Unogona kutarisa kukodzera kwemutengesi, kuita uye ongororo yevatengi uye rumwe ruzivo kuti unzwisise mukurumbira wayo uye nhanho yemhando yechigadzirwa.
