Semiconductor silicon nitride ceramics

Semiconductor silikoon nitride ceramics muuqaal leh Sawirka

Sharaxaad Gaaban:

Silikon nitride waxay leedahay iska caabin shoog kulayl ah oo ka wanaagsan dhoobada kale. Marka lagu daro xoogga sare, ballaarinta kulaylka hooseeya, caabbinta daxalka wanaagsan iyo adkaanta jabka, silikoon nitride ayaa inta badan loo adeegsadaa hawada hawada ama warshadaha baabuurta. Codsiyada kale sida biraha gubanaya, farsamaynta birta dhalaalaysa, iwm. Dahaarka korantada, caabbinta daxalka wanaagsan, heerkulka hawlgalka dhexdhexaadka ah (13000C), dhoobada qaab dhismeedka, sifooyinka farsamada wanaagsan, balaadhinta kulaylka hooseeya, dhaqdhaqaaqa kulaylka sare, xasilloonida shoogga kulaylka oo aad u wanaagsan, hooseeya gaar ahaan cuf-jiid.

Silikon nitride waa dhoobo cawl leh oo leh jab adag oo jaban, iska caabin shoog kulayl oo aad u fiican, iyo sifooyin aan la dabooli karin oo biraha dhalaalay.

Iyada oo la adeegsanayo sifooyinkan, waxaa lagu dabaqaa qaybaha matoorka gubashada gudaha sida qaybaha mishiinka baabuurta, mishiinka alxanka ee tuubooyinka, iwm, gaar ahaan qaybaha u baahan in loo isticmaalo jawi adag sida kulaylka.

Iyada oo ay iska caabbinta xirashada sare iyo xoogga farsamada sare, codsiyadeeda ee qaybaha rullaluistemadka, wareegyada usheeda dhexe iyo qalabka wax soo saarka semiconductor qaybo si joogto ah u fidin.

Astaamaha dhoobada nitride silicon

1, wuxuu leeyahay awood sare oo heerkul weyn;

2, adkaanta jabka sare;

3, xoog laabasho wanaagsan;

4, caabbinta daalka farsamada iyo gurguurta;

5, iftiin - cufnaanta hoose;

6, adkaanta sare iyo xirashada caabbinta;

7, caabbinta naxdinta kulaylka heer sare ah;

8, ballaarinta kulaylka hooseeya;

9, dahaarka korantada;

10, iska caabin oksidation wanaagsan;

11, caabbinta daxalka kiimikada wanaagsan.

Ceramics-ka Silicon nitride waxay leeyihiin iskudar balaadhinta kulaylka hooseeya iyo kulaylka kuleylka sarreeya, sidaa darteed waxay leeyihiin iska caabin naxdin leh oo kulaylka ah. Silicon nitride-ka kulul ee la riixay ma jabi doono ka dib marka lagu kululeeyo 1000 ℃ oo lagu rido biyo qabow. Heerkul aan aad u sarreyn, nitride silicon waxay leedahay awood sare iyo iska caabin saameyn leh, laakiin ka sarreeya 1200 ℃ waxay dhaawacmi doontaa koritaanka wakhtiga isticmaalka, si ay xooggeeda loo yareeyo, u nugul dhaawaca daalka ee ka sarreeya 1450 ℃, markaa isticmaalka heerkulka Si3N4 guud ahaan kama badna 1300 ℃.
