Saxanka Dhoobada ee Alumina oo Nadiif ah - loogu talagalay Dahaarka iyo Qalabka Heerkulka Sare
Saxanka dhoobada ah ee St.Cera waxaa laga sameeyay 99.8% alumina saafi ah oo sareysa (Al₂O₃), oo bixiya xoog dielectric sare (15×10⁶ V/m), xasillooni kuleyl ilaa 1600°C, iyo iska caabin aad u fiican oo xirashada ah. Saxannada waxaa lagu dhejiyay si sax ah si loo gaaro fidsanaan ≤5 μm oo ka badan 100 mm iyo qallafsanaanta dusha sare Ra ≤0.4 μm. Waxaa laga heli karaa dhumucda caadiga ah laga bilaabo 1 mm ilaa 20 mm, cabbirro gaar ah ilaa 500 × 500 mm. Waxaa loo isticmaalaa sidii dahaadh koronto, saldhigyo kuleyliye, dahaadh qol, iyo substrate-ka faakiyuumka.
Tilmaamaha (ku salaysan 99.8% Al₂O₃):
| Hantida | Qiimaha |
| Alaab | 99.8% Alumina (Ceyri) |
| Cufnaanta | 3.93 g/cm³ |
| Xoogga Dabacsanaan | 361 MPa |
| Xoogga Dielectric | 15 × 10⁶ V/m |
| Iska caabin Gaar ah | >10¹⁴ Ω·mm²/m |
| Qaboojinta Kulaylka | 32 W/m·k |
| Ballaarinta Kulaylka (25-1000°C) | 7.2 × 10⁻⁶/℃ |
| Heerkulka ugu Sareeya ee Hawlgalka | 1600°C |

Codsiyada:
- · Taarikada dahaarka korontada ee qalabka danab sare leh
- · Taarikada taageerada kuleyliyaha ee foornada faafinta
- · Dahaarka qolka ee CVD/PVD
- · Taarikada salka ee loogu talagalay qalabka faakuumka lagu shubo
Faa'iidooyinka:
- · 0% nuugista biyaha - ma jiraan wax gaas ah oo ku jira faakuumka
- · Kiimiko ahaan aan firfircoonayn - u adkaysta asiidhyada iyo halogens-ka (marka laga reebo HF)
Habayn:
Godadka, jarista, wareegsanaanta geeska, iyo biraha ayaa la heli karaa.
