Thaum Lub Yim Hli 2021, peb lub tuam txhab muab cov khoom siv silicon nitride sib txuas silicon carbide cib rau cov neeg siv khoom tshiab hauv Russia. Cov ntsiab lus silicon nitride ntau dua lossis sib npaug rau 20%, qhov porosity tsawg dua lossis sib npaug rau 17%, lub zog sib zog ntau dua lossis sib npaug rau 150MPa, cov npoo thiab cov ces kaum zoo, qhov siab kam rau ua yog ± 0.5mm, thiab saum npoo yog tiaj thiab du. Tshuaj lom neeg ua cua sov rau hydrogen corrosion tsis kam ntawm cov neeg siv khoom
Silicon nitride bonded silicon carbide cib yog lub cib ua hluav taws kub nyhiab, uas raug rho tawm ntawm 1450 ℃ hauv lub cub tawg nitrogen. Nws muaj zog tiv taus xeb, hnav zoo tiv taus thiab zoo heev thermal poob siab stability. Nws feem ntau siv hauv qhov cub nrog qhov chaw ua haujlwm hnyav xws li hlau ua rau lub tshuab ua kom tawg, cov khib nyiab pov tseg thiab cov tshuaj rauv
