Amalungu e-Silicon nitride semiconductor ceramic

ISilicon nitride semiconductor iinxalenye zeceramic Obonisiwe Umfanekiso

Inkcazelo emfutshane:

I-Silicon nitride yi-ceramic engwevu enokuqina okuphezulu kokuqhekeka, ukuxhathisa ukothuka kobushushu, kunye neempawu ezingenakungeneka kwiintsimbi ezinyibilikisiweyo.

Usebenzisa ezi mpawu, isetyenziswa kumalungu enjini yokutsha yangaphakathi anje ngeendawo zenjini yemoto, imibhobho ye-welding machine welding, njl.

Ngokumelana kwayo okuphezulu kunye namandla omatshini aphezulu, izicelo zayo ekuthwaleni iinxalenye ze-roller, iibheringi ze-shaft ezijikelezayo kunye nezixhobo zokuvelisa izixhobo ze-semiconductor ezisecaleni zihlala zisanda.

Iipropati ze-silicon nitride ceramics

I-1, inamandla aphezulu kuluhlu olukhulu lobushushu;

2, ukomelela okuphezulu kokuqhekeka;

3, ukomelela okuhle kokugoba;

I-4, ukuchasana nokudinwa koomatshini kunye nokuhamba;

5, ukukhanya - ukuxinana okuphantsi;

6, ubunzima obuphezulu kunye nokumelana nokunxiba;

I-7, ukuxhathisa ukothuka kwe-thermal;

8, ukwanda kwe-thermal ephantsi;

9, i-insulator yombane;

I-10, ukuxhathisa okulungileyo kwe-oxidation;

I-11, ukuxhathisa okulungileyo kokubola kweekhemikhali.

I-Silicon nitride ceramics ine-coefficient ephantsi yokwandiswa kwe-thermal kunye ne-conductivity ephezulu ye-thermal, ngoko ke inokumelana nokutshatyalaliswa kobushushu. I-silicon nitride ecinezelekileyo ecinezelekileyo ayizukwaphuka emva kokuba ifudunyezwe kwi-1000℃ kwaye ifakwe emanzini abandayo. Kwiqondo lobushushu elingekho phezulu kakhulu, i-silicon nitride inamandla amakhulu kunye nokumelana nempembelelo, kodwa ngaphezulu kwe-1200 ℃ iya konakaliswa ngokukhula kwexesha lokusetyenziswa, ukuze amandla ayo ancitshiswe, athandeke ngakumbi kumonakalo wokudinwa ngaphezulu kwe-1450 ℃, ngoko ke ukusetyenziswa. yeSi3N4 iqondo lobushushu alidluli kwi-1300℃.
