Njirimara na isi ojiji nke silicon carbide mmeghachi omume

Njirimara silicon carbide mmeghachi omume na ojiji ndị bụ isi? Silicon carbide nwekwara ike na-akpọ carborundum ma ọ bụ fireproof ájá, bụ inorganic compound, kewara green silicon carbide na black silicon carbide abụọ. Ị maara njirimara na isi ojiji nke silicon carbide? Taa, anyị ga-ewebata akụrụngwa na isi ojiji nke silicon carbide.

silicon carbide reactive sintering silicon carbide bụ ojiji nke quartz ájá, calcined mmanụ ala coke (ma ọ bụ coal coking), osisi slag (mmepụta nke green silicon carbide kwesịrị ịgbakwunye nri nnu) na ndị ọzọ akụrụngwa, site na ọkụ ọkụ ọkụ ọkụ na-aga n'ihu elu okpomọkụ agbaze.

Njirimara nke silicon carbide na-emeghachi omume:

1. Thermal conductivity na thermal mgbasa ọnụọgụ nke silicon carbide. Dị ka ụdị refractory ihe, carbonized brik nwere magburu onwe iguzogide ujo. Nke a na-apụtakarị n'ike ọkụ ọkụ ya (ọnụọgụ nnyefe ọkụ) yana ọnụ ọgụgụ dị ala nke mgbasawanye thermal.

2, conductivity nke silicon carbide. Silicon carbide bụ ihe semiconductor, ihe omume ya dịgasị iche na ụdị na ọnụ ọgụgụ adịghị ọcha ewepụtara n'ime crystallization, na nguzogide dị n'etiti 10-2-1012Ω · cm. N'ime ha, aluminom, nitrogen na boron nwere mmetụta dị ukwuu na conductivity nke silicon carbide, na conductivity nke silicon carbide na ihe aluminom na-abawanye nke ukwuu.

3. Nguzogide silicon carbide. Nguzogide nke silicon carbide na-agbanwe na mgbanwe nke okpomọkụ, ma n'ime ụfọdụ ọnọdụ okpomọkụ na àgwà okpomọkụ nke metal resistor na-atụgharị. Mmekọrịta dị n'etiti nguzogide na okpomọkụ nke silicon carbide dị mgbagwoju anya. Ihe omume nke mmeghachi omume nke silicon carbide na-abawanye na okpomọkụ na-ebili na uru ụfọdụ, na conductivity na-ebelata mgbe okpomọkụ na-ebili ọzọ.
