Claikon Nitride: Giraanta warshadaha ee futon Nitride

Digaladihii Silicon Nitride (SI3N4) waxay leeyihiin wax qabad aad u wanaagsan, laakiin guryaha farsamada liita oo si fudud ayaa loo cayimay heerkulka sare.

Tilmaamaha:

1. Si3n4 wuxuu leeyahay mid taban oo ah ballaarinta kuleylka kuleylka iyo jiritaanka heerkulka sare, taasoo dhalisay iska caabin naxdin leh oo si fiican u qalbi qabow. Silicon-ka kulul ee kulul ee silicon ah ma dillaaci doono xitaa marka lagu kululeeyo 1000 ° C oo lagu dhejiyo biyo qabow.

2. Silicon Nitride Claideic waa shey toonta ah oo aan hoos u dhicin inta lagu gudajiro hawsha ku dhaca. Silicon Nitride aad ayuu u xoog badan yahay, gaar ahaan silicon Nitride, oo ah mid ka mid ah walxaha ugu adag adduunka. Waxay leedahay xoog sare, cufnaan hoose, iyo iska caabin heerkul sare ah.

3. Heerkulka dhexdhexaad ah, SI3N4 wuxuu soo bandhigayaa xoog sare iyo iska caabin saamayn leh. Si kastaba ha noqotee, oo ka sarreysa 1200 ° C, oo waqti ka dib, taasoo dhalisay hoos u dhac ku dhaca.

4. Dhibaatada daalka waxay u badan tahay inay ka badnaato 1450 ° C, sidaa darteed heerkulka qalliinka ee SI3N4 guud ahaan wuxuu ku xaddidan yahay 1300 ° C.
