Izixhobo zeCeramic ze-Alumina ezicocekileyo eziphezulu zeSemiconductor kunye nezicelo zeMizi-mveliso
I-St.Cera ivelisa iindawo ze-ceramic ze-alumina ezichanekileyo (Al₂O₃) ngokweemfuno zabathengi. Zisebenzisa i-alumina ene-99.8% ephezulu-ecocekileyo, ezi zinto zibonelela ngamandla agqwesileyo okugoba (361 MPa), ubunzima obuphezulu (16 GPa), kunye namandla abalaseleyo e-dielectric (15×10⁶ V/m). Zenzelwe izixhobo ze-semiconductor, ii-assembly ezinganyangekiyo, ii-insulators zombane, kunye nezixhobo zobushushu obuphezulu, ezi zinto zibonelela ngokufunxwa kwamanzi okuphantse kube zero (0%) kunye ne-coefficient yokwandiswa kobushushu ye-7.2×10⁻⁶/℃, ukuqinisekisa uzinzo olulinganayo phantsi kweemeko ezinzima.

Izicelo:
- · Iilayini zegumbi leenkqubo ze-semiconductor, iindawo zokujonga, kunye neepleyiti zokusasaza igesi
- · Iibhantshi ezingagugiyo, iiringi zokuvala, kunye neebhola zokubeka iibheringi
- · Izithinteli zombane ezine-voltage ephezulu kunye nezithinteli ze-spark plug
- · Izixhobo zesithando somlilo, izixhasi zesifudumezi, kunye neetyhubhu zokukhusela i-thermocouple
Inkqubo yoMveliso:
Ukucinezela okungabonakaliyo → ukuchwetheza okuluhlaza → ukucocwa kwe-sintering kwi-1600°C → Ukusila/ukulepha ngokuchanekileyo kwe-CNC → ukucocwa kwe-ultrasonic → Ukuhlolwa kobukhulu be-100% ye-CMM. Iijiyometri ezintsonkothileyo, iindonga ezibhityileyo (≥0.5 mm), kunye nokunyamezelana okuqinileyo (ukuya kuthi ga kwi-±0.01 mm) zifezekiswa rhoqo.
Ulawulo lwemeko:
Iqinisekiswe yi-ISO 9001:2015. Ibhetshi nganye ivavanywa amandla okugoba (ukugoba kwamanqaku ama-3), ubulukhuni (iiVickers), amandla e-dielectric (ASTM D149), kunye nokumelana nobushushu (ii-cycles ezili-10, i-25°C ↔ 1000°C). Akukho mifantu okanye iitships ezibonakalayo phantsi kwe-20× microscopy.
Iingenelo ngaphezu kweenxalenye zesinyithi okanye ze-polymer:
- · 3–5× nzima kunentsimbi engagqwaliyo (16 GPa vs. ~2 GPa)
- · Ayisebenzi ngokweekhemikhali — ayixhathisi kwii-asidi, ii-alkali, kunye nee-halogens (ngaphandle kwe-HF)
- · Isigqubutheli sombane >10¹⁴ Ω·cm, esivumela ukusetyenziswa kwiindawo ezine-voltage ephezulu
- · Inkonzo eqhubekayo ukuya kuthi ga kwi-1600°C, idlula kakhulu imida yesinyithi okanye iplastiki
Ukwenziwa ngokwezifiso:
Siyayamkela imizobo yabathengi (ifomathi ye-STEP/IGS) kwaye sinikezela ngeprototyping ekhawulezayo (iiveki ezi-2-3). Iinxalenye zingabonelelwa njengezisinkiweyo, ezicoliweyo, ezirhangqiweyo, okanye ezipholishiweyo (Ra ≤0.05 μm). Ii-edge rounding, ii-counterbores, imingxunya enemisonto, kunye nee-vacuum grooves ziyafumaneka.
Qaphela: Kwizicelo ezifuna ukomelela okuphezulu kokuqhekeka, cinga ngeendawo ze-zirconia (ZrO₂). Ukuze ufumane ukuhanjiswa kobushushu okuphezulu, jonga kwiimveliso zethu ze-BeO okanye ze-Si₃N₄. Yonke idatha engentla ilandela ngokungqongqo itafile yepropathi ye-Al₂O₃ enikiweyo (umgangatho we-99.8%).
