Siliconized Graphite vs. Sic

Carbon graphite zvinyorwa zvine udzikunje, simba rakanyanya rekupokana, kuparara kwakanyanya, kupfeka, indasitiri yakawandisa, indasitiri yemakemikari, petroleum, pupps, pombi uye mamwe minda uye mamwe minda uye mamwe minda uye mamwe minda uye mamwe minda uye mamwe minda uye mamwe minda uye mamwe minda. Zvigadziriso zveGrathijitari hazvina kuderera pane kupfeka kupokana uye kupokana, nepo grasition yechiGransering, ine zvivakwa zvekaramu uye silicon carbide, uye inoshandiswa mune dzakasiyana siyana dzekushandisa.

Chii chinonzi graphite silicide?

Siliconized Graphite inzvimbo yekuumbwa yakaumbwa yeiyo silicon carbide layer yakafukidzwa pamusoro pegwaro regirazi. Silicon carbide layer goutic ye1 ~ 1.5mm, silicon carbide layer uye graphite matrix yakasanganiswa zvakanyanya. Iko kuomarara kwechifemberi silicid ndeyekuoma kweiyo sic, iyo yechipiri chete kuDhaimani, Boron nitride, boron baroni, uye yakakwirira kupfuura kuomarara kwe tungsten carbide uye aluminium trioxide.

Graphite silicide kwete chete yekuzvimiririra kweCarbon graphiti zvinhu, magetsi akanaka, oxidation kupokana, kurwisa kwemakemikari kurwisa silicon carbide, uye inonyanya kukodzera Mitoro inorema, kupisa kwakanyanya, uye zvimwe zviitiko zvekupembera, saka zviitiko zvekupfava zvakadzama zvakanyanya mumunda wekuisa chishandirwi, indasitiri yemakemikari, metallurgy

Kugadzirira kweGraphite Silicide

Kune matatu main main methroction nzira dze graphite silicide yemakemikari epurition

1. Chemical Vapor Deposition (CVD)) nzira

Iyo gasi ine silicon uye kabhoni kuburikidza neyakawisira tembiricha subray subhts suby yekushambadzira, inoburitsa Sic yakaiswa pamusoro peiyo substite substate. Zvishandiso zvakagadzirwa zveTrichlomethlassilane (ch3sic3), silicon tetrachloride, hydrogen, silicon vapor uye zvichingodaro. Iyo yekuisa tembiricha yakasimba yakafara, kubva kuna 1175 × kusvika 1775 ℃. SIC Layer inogadzirwa nenzira iyi yakanyanya, yunifomu mativi, dura rinoda kupaza, pedza.

2. Chemical Vapor Phase Reaction (CVR) nzira

Zvishandiso zvakagadzirwa zveCoke POWDER uye akawandisa jecha SILICA poda, painopindirwa na2000 SIC Layer uye carbon Substrate maviri haana kana shanduko iri pachena, munyaya yekuchinja kamwe kamwe, , saka chengetedza chimiro cheushe chekabhoni substrate. Nekudaro, nzira yeCVR ndiyo yekuita kweGasi yekupinda muCarbon Matrix, apo, iyo ichishandiswa sechinhu chisingaenzaniswi, zvakakodzera kushandisa resination kana cvd nzira yekuzadza pores .

3. Liquid Silicon Formeation

Iyi nzira zvakare ndeyorudzi rweCVR. Pasi peVafuum mamiriro ezvinhu, anopisa kusvika 1700-1900 ℃, kabhoni substrate yakanyudzwa zvakananga muLilicon Liquid, mvura sizi zvishoma nezvishoma inopinda muCarbon Substrate, kuita kwakaitika kuburitsa sic. 99.9999% yezvinhu zvakabikwa kune yakachena silicon. SIC Layer ukobvu kweinosvika 3.5 mm. Mushure mekuita, iyo kabhoni substrate ine 17% yemusununguko emahara kuti izadze iyo nheyo yeiyo pore, kuitira kuti substrate yave dense uye isingakwanisi. Nekudaro, iko kuvapo kwesimbi yemahara kunoderedza kupesana kwecorosi uye yakakwirira-tembiricha oxidation kuramba yeiyo silicified graphiti.

Musiyano pakati peSiliconized graphite uye sic

1.Inliconized graphite (siliconized graphite) inzvimbo inosanganiswa yakaumbwa neiyo silicon carbide layer yakafukidzwa pamusoro pegwaro regirazi. Siliconized graphite kuomarara kweSIC Graphite Silicide inogona kushandiswa sePhosphoric acid, phosphorous ambine uye hydrofluor acid pombi pombi. Uye zvakare, iyo Silmonductor Indasitiri, seSilicon Epitaxial Ekukura kweiyo kupisa subs substrate uye kugadzirwa uye kugadzirwa kwemagetsi ekugadzira, marara emazino, midzi yemazino emazino.

2.SILICON CARBIDE (SIC) yakagadzirwa neQuartz Sand, Petroleum Coke (kana maCoke Offic) Silicon cartodi iripowo mune zvakasikwa seyakareba mineral, Moissanite. Silicon carbide inozivikanwawo seCarbon Silica. MuContemporary C, N, B Uye Zvimwe zvisiri-oxide yakakwirira-Tech Repractory Parizvino, kugadzirwa kweChina cheChinese cheSilicon Carbide yakakamurwa muBlack Carbide marudzi maviri, its exgarnal makristuru maviri, 20 ~ 3, microharns of 2840 ~ 3320kg / mm2

Chii chinonzi graphite silicide uye maindasitiri ayo anoshandiswa mairi?

Siliconized Graphite ndeyemidziyo inosanganisira iyo silicon carbide layer yakaiswa pamusoro pegwaro regiramura. Kuomesa kweGrathi SiliciDide ndiko kuomarara kweSIC, iyo yechipiri chete kuDhaimondi, Boron Nitride, Boron buri, uye yakakwirira kupfuura tungsten carbide uye aluminium trioxide. Graphite Silicide inogona kushandiswa sePhosphoric acid, phosphoric acid uye hydrofluor acid pombi ye pombi. Uye zvakare, iyo Silmonductor Indasitiri, seSilicon Epitaxial Ekukura kweiyo kupisa subs substrate uye kugadzirwa uye kugadzirwa kwemagetsi ekugadzira, marara emazino, midzi yemazino emazino. Silicon carbide inogadzirwa kubva kuQuartz Sand, Petroleum Coke (kana maCoke Coke), munyu unowedzerwa kuti ubudise green silicon carbide) uye zvimwe zvigadzirwa zvine mitsara nekunyanyisa kupisa mune choto chakapokana. Silicon cartodi iripowo mune zvakasikwa seyakajairira mineral, Moissanite. Silicon carbide inozivikanwawo seCarbon Silica. MuContemporary C, N, B Uye Zvimwe zvisiri-oxide yakakwirira-Tech Repractory Parizvino, kugadzirwa kweChina cheChinese kwechigadzirwa cheSilicon chakakamurwa kuita marudzi maviri esticon baricon uye green siltagson carbide

Graphite silicide serudzi rweSilicon Cardide yakasimbiswa graphi Kuwedzera kwekuwedzera, izvo zvinogona kuiswa pazvisimbiso zvemakanika uye zvimwe zvikamu zvepamusoro-zvakakwirira.

Chiso chekupedzisira chechisimbiso chechikwata chechisimbiso chakaumbwa nechisimbiso cheDynamic chakamiswa pamusoro pechigaro, chinoda kuti zvinhu zvakanaka zviite kupokana, kuderera kwekukakavara, kupokana, kupokana, uye kusimba kwesangano kwakasimba, uye graphiti yetsika inogona kunyatsoita izvi zvinodiwa. Iyo inoyerwa, apo iyo PV Kukoshesa m / s pasina kukuvara. Kuwedzera inogona zvakare kushandiswa kune yekuvhara pombi uye yakakwirira-polel yeinjini mvura yemvura inosimbisa uye zvimwe zvisimbiso. Graphite Silicide inogona kushandiswa sePhosphoric acid, phosphoric acid uye hydrofluor acid pombi ye pombi. Uye zvakare, iyo Silmonductor Indasitiri, seSilicon Epitaxial Ekukura kweiyo yekudziya plate subtrate uye kugadzirwa uye kugadzirwa kwemagetsi ekugadzira, midzi yekugadzira midzi, etot.

Zadza fomu redu pfupi rekubvunza nhasi kuti utaure zvakananga nemumwe weinjiniya edu ane ruzivo rwekushandisa.
