Si3N4 allon kewayawa suna samun aikace-aikace a masana'antu kamar sararin samaniya, tsaro, da mai da iskar gas, inda aminci da dorewa suke da mahimmanci. Bugu da ƙari, silicon nitride yana da kyawawan kaddarorin masu hana wutar lantarki, yana mai da shi kyakkyawan zaɓi don aikace-aikacen ƙarfi mai ƙarfi.

4. LTCC (ƙananan zafin jiki co-kore yumbu) allon kewayawa:

Ana kera allunan kewayawa na LTCC ta amfani da kaset ɗin yumbu masu yawa waɗanda aka buga a allo tare da tsarin gudanarwa. Ana tattara yadudduka sannan a harba su a cikin ƙananan yanayin zafi, suna ƙirƙirar allon kewayawa mai yawa kuma abin dogaro. Fasahar LTCC tana ba da damar abubuwan da ba za a iya amfani da su ba kamar su resistors, capacitors da inductors don haɗa su a cikin hukumar da'ira da kanta, suna ba da izinin ƙaranci da haɓaka aiki. Waɗannan allunan sun dace da sadarwa mara waya, na'urorin lantarki, da na'urorin likitanci.

5. HTCC (high zazzabi co-kore yumbu) kewaye allon:

Kwamfutar kewayawa ta HTCC sun yi kama da allon LTCC dangane da tsarin masana'antu. Koyaya, ana harba allunan HTCC a yanayin zafi mafi girma, yana haifar da ƙara ƙarfin injina da yanayin zafi mai girma. Ana amfani da waɗannan allunan a aikace-aikacen zafi mai zafi kamar na'urori masu auna firikwensin mota, na'urorin lantarki na sararin samaniya, da kayan aikin haƙo ƙasa. Allon kewayawa na HTCC suna da kyakkyawan yanayin yanayin zafi kuma suna iya jure matsanancin hawan keke.
