Menene kewayon zafin jiki na zirconium crucibles?

Zirconium crucibles suna da babban zafin jiki, yana sa su dace da aikace-aikacen masana'antu iri-iri da suka shafi narkewar ƙarfe da sauran matakan zafin jiki. Matsakaicin zafin jiki na zirconium crucibles yawanci yana ƙaru daga zafin ɗaki zuwa kusan 2400°C (4352°F). Wannan babban ƙarfin zafin jiki ya sa zirconium crucibles ya dace don narkar da manyan ƙarfe masu narkewa kamar titanium, nickel da sauran ƙananan ƙarfe.

Bugu da ƙari, juriya na lalata zirconium da ikon jure yanayin zafi ya sa ya zama abu mai mahimmanci don aikace-aikace a cikin matsanancin yanayi.

Menene bambanci tsakanin alumina da zirconia crucible?

Alumina da zirconia crucibles ana amfani da su a cikin aikace-aikacen zafin jiki mai girma, amma suna da wasu bambance-bambance masu mahimmanci:

1. Abun abun ciki:
- Alumina crucibles an yi su da aluminum oxide (Al2O3), wani yumbu abu da aka sani da high thermal conductivity da kuma m sinadaran juriya.
- Zirconia crucibles, a gefe guda, an yi su da zirconium dioxide (ZrO2), wanda aka sani da zirconia. Zirconia yana da babban ƙarfi, tauri da juriya ga girgizar thermal.

2. Abun narkewa:
- Aluminum oxide yana da babban wurin narkewa, yawanci a kusa da 2050 ° C (3722 ° F), yana sa ya dace da aikace-aikacen zafin jiki iri-iri.
- Zirconia yana da wurin narkewa mafi girma, yawanci a kusa da 2700 ° C (4892 ° F), yana sa ya dace da aikace-aikacen da ke buƙatar matsanancin zafi.

3. Thermal conductivity:
- Aluminum oxide yana da ingantacciyar haɓakar haɓakar thermal, wanda ke da fa'ida a wasu aikace-aikace inda ingantaccen canjin zafi yana da mahimmanci.
- Zirconia yana da ƙananan ƙarancin wutar lantarki idan aka kwatanta da alumina, wanda ke da fa'ida a cikin aikace-aikacen da ke buƙatar rufin thermal.

4. Juriya na sinadarai:
- Aluminum oxide yana da kyakkyawan juriya na sinadarai, yana mai da shi dacewa don amfani da narkakkun karafa da yawa da kuma yanayin sinadarai masu tsauri.
Zirconia kuma yana nuna kyakkyawan juriya na sinadarai, musamman ga yanayin acidic da alkaline, yana mai da shi dacewa da buƙatar aikace-aikacen sinadarai.

A taƙaice, yayin da duka alumina da zirconia crucibles sun dace da aikace-aikacen zafin jiki mai zafi, zaɓin tsakanin su biyun ya dogara da takamaiman buƙatu kamar kewayon zafin jiki, haɓakar thermal, da juriya na sinadarai.
