Thaum qis dua 40.2 degree, nws muaj peev xwm crystallize nyob rau hauv ib tug aqueous tov muab dihydrate KF·2H2O, uas yog monoclinic, nws yog nws tus kheej-solved crystalline dej ntawm 41 degree. Nws tuaj yeem tau txais los ntawm thermal decomposition ntawm potassium hydrogen fluoride lossis potassium carbonate (lossis potassium hydroxide) thiab hydrofluoric acid (40% lossis anhydrous). Nws tuaj yeem siv rau iav engraving, khaws cia zaub mov, nws tuaj yeem siv los ua vuam flux, fluoride, tshuaj tua kab, thiab lwm yam. Daim duab 1 tus qauv qauv ntawm potassium fluoride. |
| Siv | Anhydrous Potassium fluoride yog siv nyob rau hauv cov organic synthesis raws li catalyst rau ntau yam tshuaj, los yog qhia fluorine rau hauv cov organic molecules. Piv txwv li, cov tshuaj fluoro tuaj yeem npaj tau los ntawm kev hloov cov tshuaj chlorine atoms los ntawm fluorine atoms, xws li hauv kev tsim cov sodium fluoroacetate, tshuaj lom nas. Lub zog nucleophilic ntawm F- thiab solubility ntawm KF hauv aprotic organic solvents tuaj yeem txhim kho los ntawm kev siv cov yas ethers. Qhov "liab qab" fluoride ion tau txais yog ib qho fluorinating tus neeg ua haujlwm zoo. |
| Kev npaj | Potassium fluoride yog npaj los ntawm reacting potassium carbonate (los yog KOH) nrog aqueous hydrofluoric acid. Kev saib xyuas yog qhov tsim nyog hauv kev tuav cov ntsev anhydrous, txhawm rau tiv thaiv nws cov dej. |
| Chemical Properties | Dawb, crystalline, deliquescent hmoov; ntse saline saj.Soluble nyob rau hauv dej thiab hydrogen fluoride, insoluble nyob rau hauv cawv. |
| Chemical Properties | Potassium fluoride yog dawb crystalline khoom. |

| Siv | Potassium fluoride yog siv rau hauv cov hlau tiav, roj teeb, coatings thiab cov tshuaj yees duab. Nws yog siv rau kev kawm txog ion-specific o thiab de-o ntawm ampholytic polymer gels nrog rau kev ntsuas hluav taws xob polarizabilities ntawm ions hauv polymers ntawm alkali halides. Nws pom daim ntawv thov hauv kev lag luam hluav taws xob ua cov khoom siv kho mob hlau. Nws yog siv los ua preservative, khoom noj khoom haus additive, catalyzer thiab dej absorbing tus neeg sawv cev. Hauv Finkelstein cov tshuaj tiv thaiv, nws tau koom nrog kev hloov pauv ntawm chlorocarbons rau fluorocarbons siv cov kuab tshuaj polar xws li dimethyl formamide thiab ethylene glycol. |
