Tungsten Crucible
Tungsten crucible
Kagwiritsidwe: Chifukwa cha kukana kwake kutentha ndi kutsika kochepa, tungsten imagwiritsidwa ntchito kwambiri popanga ruby ndi safiro kukula kwa kristalo ndi kusungunula kwapadziko lapansi kosowa m'makampani a LED.
Kukula komwe kuli pansipa:
| Diameter (mm) | Makulidwe (mm) | Kutalika (mm) |
| 30-50 | 2-10 | ＜1300 |
| 50-100 | 3-15 | |
| 100-150 | 3-15 | |
| 150-200 | 5-20 | |
| 200-300 | 8-20 | |
| 300-400 | 8-30 | |
| 400-450 | 8-30 | |
| 450-500 | 8-30 |
Ma crucibles athu opanikizidwa opangidwa ndi tungsten amakhala ndi makulidwe osakwana 0.8 µm. Sapphire ikhoza kuchotsedwa ku crucible popanda zovuta komanso popanda kuwononga pamwamba pa crucible. Kwa opanga safiro, izi zimapangitsa kuti pakhale kukonzanso kosavuta komanso kokwera mtengo pamwamba pa crucible. Zozungulira zimayenda bwino komanso zimapereka ma ingots apamwamba kwambiri. Ndipo palinso ubwino wina: Pamwamba posalala simatenthedwa ndi dzimbiri chifukwa champhamvu yosungunuka ya safiro. Izi zimawonjezera moyo wautumiki wa ma tungsten crucibles ogwiritsidwanso ntchito.
Titha kukonza tungsten rhenium mu makulidwe osiyanasiyana ndi ma tungsten flakes osowa kusungunula kwa nthaka ndi tungsten ndi molybdenum mbali zotentha za safiro kristalo kukula ng'anjo (kuphatikiza kutentha chishango, kutentha thupi ndi thandizo, etc.) malinga ndi zofuna za makasitomala.
