Nto oxidation ntawm silicon carbide rods siv los tsim silicon dioxide nyias zaj duab xis

Thaum siv, qhov saum npoo ntawm silicon carbide qws oxidizes los ua silicon dioxide zaj duab xis. Kev siv ntev ntev ua rau cov yeeb yaj kiab silicon dioxide thiab cov nqi tiv thaiv ntawm silicon carbide pas nrig. Cov silica zaj duab xis tau dhau los ua qhov txawv txav thiab kev cog lus ze ntawm qhov tseem ceeb ntawm crystallization (270 degree). Vim qhov hloov pauv tsis tu ncua ntawm qhov kub thiab txias thaum lub sijhawm siv cov khoom siv sib txuas, silicon dioxide zaj duab xis tau rov ua dua kom nrawm oxidation. Yog li ntawd, thaum qhov kub ntawm qhov hluav taws xob hluav taws xob hluav taws xob poob rau hauv chav tsev kub, qhov kev tiv thaiv feem ntau nce sharply. Yog tias qhov tseem ceeb ntawm silicon carbide rods sib txawv, lub load ntawm silicon carbide rods nrog siab tsis kam yog ntau concentrated thaum kev cob cog rua nyob rau hauv series, uas yuav yooj yim ua rau ib tug sai nce nyob rau hauv cov kev tiv thaiv ntawm ib co silicon carbide pas nrig thiab ib tug luv luv lifespan. Silicon carbide rods feem ntau yog siv ua ke nrog cov kab sib txuas thiab cov xaim sib txuas. Nws raug nquahu kom siv ob txoj kev sib txuas ua ke ua ib pab pawg thiab tom qab ntawd ntau qhov kev sib txuas ua ke. Tshwj xeeb tshaj yog thaum qhov kub hauv lub cub tawg tshaj 1350 degree, nws yuav tsum tau txuas nrog rau qhov sib npaug. Nws raug nquahu kom siv qhib delta thaiv rau kev xaim peb-theem.
