Sassan Ceramic na Alumina Masu Tsarkakakku don Semiconductor & Aikace-aikacen Masana'antu
St.Cera tana ƙera sassan yumbu na alumina mai inganci (Al₂O₃) bisa ga ƙa'idodin abokan ciniki. Ta amfani da alumina mai tsabta 99.8%, waɗannan sassan suna ba da ƙarfin lanƙwasa mai kyau (361 MPa), tauri mai yawa (16 GPa), da ƙarfin dielectric mai ban mamaki (15×10⁶ V/m). An ƙera su don kayan aikin semiconductor, kayan haɗin da ba sa jure lalacewa, masu hana wuta, da kayan aiki masu zafi, kayan suna ba da kusan sifili na shan ruwa (0%) da kuma ma'aunin faɗaɗa zafi na 7.2×10⁻⁶/℃, wanda ke tabbatar da daidaiton girma a ƙarƙashin yanayi mai tsauri.
Bayani dalla-dalla(bisa ga 99.8% Al₂O₃):

Aikace-aikace:
- · Layukan ɗakin sarrafa iskar gas, tashoshin kallo, da kuma faranti na rarraba iskar gas
- · Bushings masu jure lalacewa, zoben hatimi, da ƙwallan ɗaukar kaya
- · Masu hana wutar lantarki mai ƙarfin lantarki da masu hana walƙiya
- · Kayan aikin murhu, tallafin hita, da bututun kariya na thermocouple
Tsarin Masana'antu:
Matsi na Isostatic → injin kore → yin sintering a 1600°C → Niƙa / Lapping daidai na CNC → Tsaftacewa ta ultrasonic → Duba girman CMM 100%. Ana samun daidaitattun siffofi masu rikitarwa, ganuwar siriri (≥0.5 mm), da juriya mai tsauri (har zuwa ±0.01 mm) akai-akai.
Sarrafa Inganci:
An tabbatar da ISO 9001:2015. Ana gwada kowace rukuni don ƙarfin lanƙwasa (lanƙwasa maki 3), tauri (Vickers), ƙarfin dielectric (ASTM D149), da juriya ga girgizar zafi (zagaye 10, 25°C ↔ 1000°C). Babu fashewar ko guntu da ake gani a ƙarƙashin na'urar duba hoto ta 20×.
Fa'idodi akan Sassan Karfe ko Polymer:
- · 3–5× tauri fiye da bakin karfe (16 GPa idan aka kwatanta da ~2 GPa)
- · A cikin sinadarai marasa aiki — yana jure wa acid, alkalis, da halogens (banda HF)
- · Insulator na lantarki >10¹⁴ Ω·cm, wanda ke ba da damar amfani da shi a cikin yanayin wutar lantarki mai ƙarfi
- · Ci gaba da aiki har zuwa 1600°C, wanda ya wuce iyakar ƙarfe ko robobi
Keɓancewa:
Muna karɓar zane-zanen abokin ciniki (tsarin STEP/IGS) kuma muna ba da samfurin samfuri cikin sauri (makonni 2-3). Ana iya samar da sassa a cikin siminti, a niƙa, a lanƙwasa, ko a goge su (Ra ≤0.05 μm). Ana samun zagayen gefuna, ramukan counterbore, ramukan zare, da ramukan injin tsabtace iska.
Lura: Don aikace-aikacen da ke buƙatar ƙarin tauri na karyewa, yi la'akari da sassan zirconia (ZrO₂). Don mafi girman ƙarfin lantarki na zafi, duba samfuran BeO ko Si₃N₄ ɗinmu. Duk bayanan da ke sama suna bin teburin mallakar Al₂O₃ da aka bayar (matakin 99.8%).
