Isi ojiji nke Silicon Carbide

A na-eme carbide silicon carbide sitere na ájá quartz na mmanụ ala coke silica dị ka ihe ndị bụ isi sitere na mgbaze ọkụ dị elu n'ime ọkụ na-eguzogide. Isi ike ya dị n'etiti corundum na diamond, ike ọrụ ya dị elu karịa corundum, ọ na-agbajikwa ma dị nkọ. A na-esi na petroleum coke na silica na-emepụta ihe ndị bụ isi, na-etinye nnu dị ka mgbakwunye, ma gbazee na okpomọkụ dị elu n'ime ọkụ na-eguzogide. Isi ike ya dị n'etiti corundum na diamond, na ike ọrụ ya dị elu karịa corundum.

Yabụ kedu ihe bụ isi ojiji nke silicon carbide?
1. Abrasives - tumadi n'ihi na silicon carbide nwere nnukwu isi ike, nkwụsi ike kemịkalụ na ụfọdụ siri ike, silicon carbide nwere ike iji rụpụta abrasives jikọtara ọnụ, ihe mkpuchi mkpuchi na ihe nchara n'efu iji hazie iko na ceramik. , Nkume, nkedo ígwè na ụfọdụ ndị na-abụghị ferrous ọla, carbide, titanium alloy, elu-ọsọ ígwè ọnwụ ngwaọrụ na egweri wiil, wdg.

2. Refractory ihe na corrosion-eguzogide ihe --- tumadi n'ihi na silicon carbide nwere nnukwu agbaze ebe (ogo nke decomposition), chemical inertness na thermal ujo na-eguzogide, silicon carbide nwere ike iji abrasives na seramiiki ngwaahịa firing kilns. Awụsara efere na saggers, silicon carbide brik maka vetikal cylinder distillation ọkụ na zinc smelting ụlọ ọrụ, aluminum electrolytic cell lining, crucibles, obere ọkụ ọkụ na ndị ọzọ silicon carbide seramiiki ngwaahịa.

3. Kemịkalụ ojiji-n'ihi na silicon carbide nwere ike decompose na a wụrụ awụ nchara na-emeghachi omume na oxygen na metal oxides na a wụrụ nchara nchara na-emepụta carbon monoxide na silicon-nwere slag. Ya mere, enwere ike iji ya dị ka ihe na-eme ka ọ dị ọcha maka ịgbaze ígwè, ya bụ, dị ka deoxidizer na nkedo nhazi nhazi maka ịmepụta ígwè. Nke a na-ejikarị silicon carbide dị ọcha belata ọnụ ahịa. Enwere ike iji ya dị ka akụrụngwa maka imepụta silicon tetrachloride.

4. Ngwa eletriki - eji eme ihe dị ka ihe na-ekpo ọkụ, ihe ndị na-eguzogide ihe na-adịghị na ntanetị na ihe ndị dị elu nke semiconductor. Ihe ndị na-ekpo ọkụ dị ka silicon carbon mkpanaka (nke dabara maka ọkụ eletrik dị iche iche na-arụ ọrụ na 1100 ruo 1500 ° C), ihe ndị na-eguzogide ihe na-abụghị linear, na valves nchebe ọkụ dị iche iche.
