Gịnị bụ tantalum carbide

Tantalum carbide (TaC)bụ ihe seramiiki ultra-elu okpomọkụ nke nwere oke okpomọkụ na-eguzogide, nnukwu njupụta, elu compactness; ịdị ọcha dị elu, ọdịnaya adịghị ọcha <5PPM; na kemịkalụ inertness na amonia na hydrogen na okpomọkụ dị elu, na nkwụsi ike dị mma.

Ihe a na-akpọ ultra-high okpomọkụ ceramics (UHTCs) na-ezokarị aka na klas nke ihe seramiiki nwere ebe mgbaze karịa 3000 ℃ ma jiri ya mee ihe na okpomọkụ dị elu na gburugburu corrosive (dị ka ikuku oxygen gburugburu) n'elu 2000 ℃, dị ka. ZrC, HfC, TaC, HfB2, ZrB2, HfN, wdg.

Tantalum carbidenwere ebe agbaze ruo 3880 ℃, nwere ike siri ike (Mohs hardness 9-10), nnukwu conductivity thermal (22W · m-1 · K-1), nnukwu agbagọ ike (340-400MPa), na obere ọnụọgụ mgbasawanye ọkụ.

Ya mere,Ihe mkpuchi TaCA na-eji ya eme ihe na nchekwa ikuku ikuku, otu kristal uto, ngwa eletrọnịkị ike, na ngwaọrụ ahụike.

Tantalum carbide (TaC)bụ onye otu ezinụlọ seramiiki ultra-high okpomọkụ!

Dị ka ụgbọ elu ọgbara ọhụrụ dị ka ụgbọ elu ikuku, rọketi, na ngwa agha na-etolite n'ebe dị elu, mkpali dị elu, na elu dị elu, ihe ndị a chọrọ maka nguzogide okpomọkụ dị elu na nkwụsị oxidation nke ihe elu ha n'okpuru ọnọdụ dị oke egwu na-adị elu na elu.
