Silicon Carbide (SiC) ntụ ntụ ntụ ntụ
Silicon carbide (SiC), nke a makwaara dị ka carborundum ma ọ bụ emery, bụ otu n'ime ihe ndị a na-ejikarị eme ihe na nke akụ na ụba. SiC dị n'ụdị abụọ: carbide silicon ojii na carbide silicon green.
Usoro mmepụta
A na-emepụta SiC site na agbaze ájá quartz, petroleum coke, ma ọ bụ coal tar, na ibe osisi na okpomọkụ dị elu n'ime ọkụ na-eguzogide. A na-eme carbide silịkọn na-acha akwụkwọ ndụ kpọmkwem site na ịgbaze silicon dioxide na mmanụ ala coke, na-agbakwunye nnu dị ka mgbakwunye.
Ngwongwo na ngwa
-isi ike:Ọdịda n'etiti corundum na diamond.
-Mechanical Ike:Dị elu karịa corundum, kenkuwa, na nkọ.
- Omume:Nwere ụfọdụ ọkụ eletrik na thermal conductivity.
N'ihi ihe ndị a, SiC dị mma maka ngwa chọrọ ogologo oge na njikwa okpomọkụ. A na-ejikarị ya eme ihe na ụlọ ọrụ dịka abrasives, refractories na semiconductor.
Akụkụ nke Silicon Carbide
1. Mgbasawanye okpomọkụ dị ala:Na-ebelata mgbanwe nha site na ngbanwe okpomọkụ.
2. High Thermal Conductivity:Na-ebufe ọkụ nke ọma.
3. Nguzogide nrụgide okpomọkụ:Na-ebelata ohere nke nrụgide okpomọkụ.
4. Magburu onwe Thermal Shock Resistance:Na-egbochi mgbanwe okpomọkụ ngwa ngwa.
5. Nguzogide corrosion:Na-adịgide adịgide megide mmebi kemịkalụ.
6. Oke oke okpomọkụ ndidi: Na-arụ ọrụ nke ọma na ma oke oyi na gburugburu ebe ọkụ.
7. Nguzogide na-ekpo ọkụ dị elu:Na-edobe nkwụsi ike na ike na oke okpomọkụ.
Semicera nwere ike hazie 4N-6N silicon carbide powder dị ka mkpa gị si dị, nabata ịjụ ajụjụ.
