Si3N4-SiC brik

Ngwaahịa a pụtara na mbu na njedebe 1960s, njirimara ya bụ na ọ na-eji Si3N4 dị ka ihe nkedo. Si3N4 dị n'etiti mkpụrụ ọka SiC n'ụdị kristal nke agịga ma ọ bụ nke nwere fibrous, ma bụrụ ihe dị mkpa dị mkpa nke ihe ọhụrụ. Ọ na-enwekarị 70% ruo 75% silicon carbide na 18% ruo 25% silicon nitride. Ọ nwere ezi corrosion eguzogide, 1400 ℃ flexural ike nke 50 ka 55MPa, na pụtara porosity nke 15%. Ọnụọgụ mgbasawanye okpomọkụ (4.5 ruo 5.0) × 10-2℃-1. A na-akwado ya site na usoro ikpo ọkụ dị elu. A na-ejikarị ya eme ihe maka ọkụ ọkụ tuyere na aluminum electrolytic cell lining. N'ime afọ ndị na-adịbeghị anya, ụlọ ọrụ anyị etinyere brik silicon nitride bonded silicon carbide brik na silicon ore furnace ọnụ na silicon mmiri akpa, nke ukwuu mma ọkụ ndụ na ọrụ ndụ nke silicon mmiri akpa.
