Semiconductor silicon nitride ceramics

Ibisobanuro bigufi:

Nitride ya Silicon ifite imbaraga zo guhangana nubushyuhe burenze ubundi bukerarugendo.Ufatanije n'imbaraga nyinshi, kwaguka k'ubushyuhe buke, kurwanya ruswa no gukomera kuvunika, nitride ya silicon ikoreshwa kenshi mu kirere cyangwa mu modoka.Ibindi bikorwa nka burner nozzles, gutunganya ibyuma bishongeshejwe, nibindi. Gukoresha amashanyarazi, kurwanya ruswa neza, ubushyuhe bwo hagati (13000C), ububumbyi bwububiko, ibikoresho byiza bya mashini, kwaguka kwinshi kwamashanyarazi, ubushyuhe bukabije bwumuriro, ibintu byiza cyane bihindagurika, uburemere.

Ibicuruzwa

Silicon nitride ni ceramic yumukara ufite ubukana buvunika cyane, guhangana nubushyuhe buhebuje, hamwe nibintu bitagereranywa byuma byashongeshejwe.

Ukoresheje ibyo biranga, bikoreshwa mubice bya moteri yaka imbere nkibice bya moteri yimodoka, imashini yo gusudira imashini zogosha, nibindi, cyane cyane ibice bigomba gukoreshwa mubidukikije nko gushyuha cyane.

Hamwe nimyenda myinshi yo kwihanganira imbaraga nubukanishi buhanitse, ikoreshwa ryayo mu gutwara ibice, uruziga ruzunguruka hamwe n’ibikoresho bitanga ibikoresho bya semiconductor bihora byiyongera.

Ibyiza bya silicon nitride ceramics

1, ifite imbaraga nyinshi murwego runini rw'ubushyuhe;

2, kuvunika cyane;

3, imbaraga nziza zo kunama;

4, kurwanya umunaniro wumukanishi no kunyerera;

5, urumuri - ubucucike buke;

6, gukomera gukomeye no kwambara birwanya;

7, uburyo bwiza bwo guhangana nubushyuhe bwumuriro;

8, kwagura ubushyuhe buke;

9, amashanyarazi;

10, kurwanya okiside nziza;

11, imiti irwanya ruswa.

Ceramics ya silicon nitride ifite coefficente yo kwaguka yubushyuhe buke hamwe nubushyuhe bwo hejuru bwumuriro, kuburyo bifite imbaraga zo guhangana nubushyuhe bwiza.Nitride ishyushye cyane ya silicon nitride ntizacika nyuma yo gushyushya 1000 ℃ igashyirwa mumazi akonje.Ku butumburuke bukabije, nitride ya silicon ifite imbaraga nyinshi kandi irwanya ingaruka, ariko hejuru ya 1200 ℃ izangirika no gukura kwigihe cyo gukoresha, kuburyo imbaraga zayo zigabanuka, bikunda kwangirika kw umunaniro hejuru ya 1450 ℃, bityo gukoresha y'ubushyuhe bwa Si3N4 muri rusange ntabwo irenga 1300 ℃.
