Tshuaj muaj pes tsawg leeg
Tus general qauv rau cov minerals mica group yog XY2–3Z4O10(OH, F)2 with X = K, Na, Ba, Ca, Cs, (H3O), (NH4); Y = Al, Mg, Fe2+, Li, Cr, Mn, V, Zn; and Z = Si, Al, Fe3+, Be, Ti. Compositions of the common rock-forming micas are given in the table. Ob peb lub ntuj mica muaj qhov kawg-membercompositions.
Kuj paub yog, dab tsi yog qhov muaj pes tsawg leeg ntawm mica?
| Mica | |
|---|---|
| Qeb | Phyllosilicates |
| Formula (repeating unit) | AB2–3(X, Si)4O10(O, F, OH)2 |
| Kev txheeb xyuas | |
| Xim | liab, rosy, silver, grey (lepidolite); ntsuab, xim av, dub (biotite); yellowish-xim av, ntsuab-dawb (phlogopite); tsis muaj xim, pob tshab (muscovite) |
Qhov thib ob, cov khoom ntawm mica yog dab tsi? Nws muaj cov thermal stability zoo, qis thermal conductivity, thiab tuaj yeem yooj yim raug rau qhov kub thiab txias yam tsis pom cov nyhuv. Mechanical: Mica Nws yog qhov nyuaj heev, muaj lub zog tensile siab, elastic, thiab nrog rau kev hloov pauv. Nws muaj zog compression loj heev thiab tuaj yeem ua machined, tuag-punched, lossis tes txiav.
Kuj tseem paub yog, dab tsi yog cov tshuaj formula rau biotite mica uas muaj poov tshuaj?
Mica Group ntawm Sheet Silicates
| Tshuaj muaj pes tsawg leeg | Biotite yog K (Mg, Fe) 3AlSi3O10 (OH) 2 Potassium hlau magnesium aluminum silicate hydroxide. Phlogopite yog KMg3AlSi3O10 (OH) 2Potassium magnesium aluminium silicate hydroxide |
|---|---|
| Cleavage | Ib qho zoo meej cleavage los tsim cov ntawv nyias nyias nyias orflakes. |
| Hardness | 2.5 mus rau 3 (mos) |
Mica nyob qhov twg?
Feem ntau daim ntawv mica yog khawb av nyob rau hauv Is Nrias teb, qhov chaw ua haujlwm cov nqi sib piv qis. Flake Mica Mining: Theflake mica ua nyob rau hauv Teb Chaws Asmeskas los ntawm ntau qhov chaw: lub pob zeb metamorphic hu ua schist raws li cov khoom siv los ntawm kev ua cov khoom siv feldspar thiab kaolin, los ntawm placer deposits, thiab los ntawm pegmatites.

Dab tsi yog limestone tshuaj muaj pes tsawg leeg?
Khoom Muag: Limestone, lub pob zeb sedimentary uas muaj feem ntau ntawm cov calcium-cov kabmob carbonate cov zaub mov calcite thiab dolomite. Calcite yog tshuaj calcium carbonate (formula CaCO3). Dolomite yog tshuaj calcium-magnesium carbonate (formula CaMg (CO3) 2)
Cov tshuaj muaj pes tsawg leeg ntawm cov cua yog dab tsi?
Cov pa roj mus tas li uas nws feem pua tsis hloov ntawm ib hnub rau ib hnub yog nitrogen, oxygen thiab argon. Nitrogen suav rau 78% ntawm cov huab cua, oxygen 21% thiab argon 0.9%. Cov pa roj xws li carbon dioxide, nitrous oxides, methane, thiab ozone yog cov pa roj carbon monoxide uas suav txog li ib feem kaum ntawm ib feem ntawm cov cua
Muaj pes tsawg hom tshuaj lom neeg muaj pes tsawg leeg?
Hauv chaw ua haujlwm muaj ob hom kev phom sij: kev noj qab haus huv thiab kev phom sij ntawm lub cev
Dab tsi yog qhov kev faib tawm ntawm cov teeb meem raws li muaj pes tsawg leeg?
Cov teeb meem tuaj yeem muab faib ua ob pawg dav: cov tshuaj ntshiab thiab cov khoom sib tov. Cov khoom ntshiab yog ib daim ntawv ntawm cov teeb meem uas muaj qhov sib xyaw ua ke thiab cov khoom uas tsis tu ncua thoob plaws hauv cov qauv. Kev sib xyaw ua ke yog kev sib xyaw ua ke ntawm ob lossis ntau lub ntsiab lus thiab / lossis cov khoom sib txuas
Dab tsi yog cov tshuaj muaj pes tsawg leeg ntawm superphosphate ntawm txiv qaub?
Superphosphate. superphosphate los yog superphosphate ntawm txiv qaub, Ca (H2PO4) 2, yog ib qho chaw tsim los ntawm kev kho pob zeb phosphate nrog sulfuric acid los yog phosphoric acid, los yog sib tov ntawm ob. Nws yog lub luag haujlwm tseem ceeb ntawm phosphate, daim ntawv ntawm phosphorus siv tau los ntawm cov nroj tsuag, thiab yog ib qho tseem ceeb tshaj plaws hauv ntiaj teb chiv
