Muaj ntau ntau txoj hauv kev tseem ceeb rau ferrosilicon nitride, nrog rau txoj kev sib xyaw flash combustion. Yuav kom txhua tus nkag siab, peb yuav qhia kom meej.
Flash combustion synthesis txoj kev, tseem hu ua ntsug nruam combustion synthesis txoj kev, yog ib tug tshiab txheej txheem tsim nyob rau hauv lub tshav pob ntawm hlau nitriding nyob rau hauv xyoo tas los. Lub ferrosilicon nitride synthesized los ntawm nws tsis muaj silicon dawb thiab yog haum rau ntau qhov ntau. Nrog kev tsim khoom tas mus li, tus nqi tsim khoom tau txo qis heev piv rau lwm txoj kev tsim khoom, uas tsuas yog sib npaug rau ib feem kaum lossis ib feem peb ntawm lwm txoj kev tsim khoom.
Lub flash combustion synthesis txoj kev ntawm ferrosilicon nitride yog mus txuas ntxiv ntxiv ferrosilicon alloy raw cov ntaub ntawv nrog ib tug particle loj ntawm 74 microns los ntawm sab saum toj ntawm lub flash furnace rau hauv ib tug nitrogen rauv ntawm 1400-1600 degrees Celsius. Lub 75 ferrosilicon alloy flashes thaum ntog nyob rau hauv high-temperature nitrogen. Nws hlawv sai sai, thiab cov generated ferrosilicon nitride ntog rau hauv cov khoom pas dej ua ke vim lub ntiajteb txawj nqus.
Ntxiv nrog rau columnar crystalline silicon nitride, me me puag ncig ntawm silicon nitride thiab ferrosilicon, ferrosilicon nitride theem npaj los ntawm flash combustion synthesis txoj kev tsuas muaj ib tug me me ntawm silicon dioxide thiab ib tug loj npaum li cas ntawm silicon dioxide nyob rau hauv lub microstructure. Qhov sib piv ntawm columnar silicon nitride siv lead ua yog siab. Cov khoom siv hlau theem muaj nyob rau hauv daim ntawv ntawm ferrosilicon thiab hlau thiab muab faib rau hauv columnar silicon nitride. Cov khoom siv crystallized wrapping muaj cov qauv xoob xoob thiab muaj zog ua haujlwm.
