| Magnesium fluoride Kev siv thiab kev sib xyaw |
| Kev piav qhia | Magnesium fluoride yog cov khoom siv los ntawm kev tsim cov hlau beryllium thiab uranium. Nws yog cov hmoov dawb dawb crystalline hmoov uas tsis tshua muaj tshuaj reactivity. Magnesium fluoride yog siv los ua flux hauv magnesium metallurgy thiab hauv kev lag luam ceramics. Magnesium fluoride tuaj yeem siv rau kev rho tawm ntawm txhuas los ntawm arc-rooj hlau alloys nrog Fe, Si, Ti, thiab C. Optical qhov rais ntawm purified magnesium fluoride uas xa lub teeb los ntawm lub tshuab nqus tsev ultraviolet (140 nm) mus rau hauv infrared (7) yog pom zoo siv los ua ultraviolet optical Cheebtsam rau siv nyob rau hauv qhov chaw tshawb nrhiav. Magnesium fluoride kuj tseem siv tau los ua cov khoom siv tiv thaiv kev cuam tshuam uas muaj cov nyhuv antireflection zoo thiab qhov ntsuas qis qis. |
| Siv | Hauv Mg metallurgy thiab hauv kev lag luam ceramics, Magnesium fluoride yog siv los ua flux. Ib qho crystals ntawm alkaline-lub ntiaj teb fluorides, xws li Magnesium fluoride, yog qhov tsim nyog rau kev siv kho qhov muag vim lawv qhov loj ntawm pob tshab los ntawm ultraviolet mus rau nruab nrab infrared cheeb tsam. Infrared pob tshab qhov rais yuav raug npaj los ntawm kub nias Magnesium fluoride hmoov. Ternary intercalation compounds ntawm graphite nrog fluorine thiab Magnesium fluoride tau npaj; cov tebchaw no muaj hluav taws xob ua tau zoo thiab yog li ntawd yuav muaj peev xwm tseem ceeb xws li cathodes lossis cov khoom siv hluav taws xob tshiab. Thaum kawg, eutectic NaF-MgF2 tau npaj siab nyob rau hauv qib siab latent-kub lub zog cia rau lub hnub ci zog. |
| Kev npaj | Magnesium fluoride yog npaj los ntawm kev kho cov tshuaj magnesium ntsev nrog hydrofluoric acid los yog sodium fluoride: MgSO4 + 2HF → MgF2 + 2H+ + SO42– los yog los ntawm kev ntxiv hydrofluoric acid rau magnesium carbonate: MgCO3 + 2HF → MgF2 + CO2 + H2O |

| Kev piav qhia | Magnesium fluoride (MgF2) yog dawb crystalline ntsev. Nws yog siv nyob rau hauv electrolysis ntawm txhuas ore los tsim metallic aluminium thiab kuj raws li ib tug reflective txheej ntawm ntau hom optical Cheebtsam. Nws yog tetragonal, birefringent siv lead ua nrog TiO2 hom qauv. |
| Chemical Properties | dawb mus rau lub teeb beige hmoov |
| Chemical Properties | Magnesium Fluoride yog cov hmoov dawb dawb crystalline hmoov nrog cov tshuaj tsis tshua muaj tshuaj. Qhov kev txheeb ze inertness no ua rau qee qhov kev siv, piv txwv li, cov yeeb yaj kiab ruaj khov ruaj khov los hloov lub teeb kis ntawm cov khoom siv kho qhov muag thiab hluav taws xob. |
| Siv | Haum rau lub tshuab nqus tsev vacuum. Magnesium fluoride tshwm sim nyob rau hauv qhov zoo li cov ntxhia, sellaite. Nws yog siv nyob rau hauv iav thiab ceramics. Ib leeg siv lead ua yog siv rau polarizing prisms thiab lo ntsiab muag. |
| Siv | Nyob rau hauv cov ceramics thiab iav kev lag luam.Magnesium Fluoride yog ib tug ruaj khov siv lead ua uas tsis muaj nqus, haum rau high-powered laser, chaw, thiab lwm yam kev siv UV. MgF2 kuj yog ib txwm muaj birefringent, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv qhov chaw no tuaj yeem siv tau, xws li daim hlau retardation thiab polarizing ntsiab lus, tshwj xeeb tshaj yog nyob rau hauv lub wavelength ntau ntawm 0.13-0.30 µm. |
| Siv | Magnesium fluoride (MgF2) yog siv los kho cov tsom iav qhov muag polarize kom txo qhov glare ntawm lub hnub ci los ntawm kev xaiv qhov taw qhia ntawm lub teeb tsis dhau ntawm lub lo ntsiab muag. MgF2 kuj yog siv los ua polarize qhov rais, looj tsom iav dub, thiab cov khoom siv kho qhov muag zoo sib xws. |
| Kev npaj | Magnesium fluoride yog cov ntsev tsis muaj xim nrog cov qauv rutile. Nws yog tsim los ntawm cov tshuaj tiv thaiv ntawm magnesium oxide thiab HF los yog magnesium carbonate thiab NH4F · HF. Nws kuj yog ib qho khoom siv los ntawm kev tsim cov khoom xws li beryllium los ntawm kev txo cov tshuaj fluoride los ntawm magnesium hlau. |
| Hazard | Muaj zog irritant. TLV: 2.5 mg (F) / m3. |
| Kev ruaj ntseg Profile | Muaj tshuaj lom los ntawm kev noj tshuaj. Thaum rhuab mus rau decomposition nws emits cov pa phem ntawm F-. Saib kuj MAGNESIUM thiab FLUORIDES. |
