What are the main uses of Sodium Zirconium (4 +) Fluoride (2:1:6)?
Sodium zirconium fluoride (2:1:6), its scientific name is sodium hexafluorozirconate, this material is quite widely used. In the industrial field, it is often used as a raw material for ceramic glazes. Applying this material to ceramics can make the glaze surface gorgeous and colorful, and enhance its wear resistance and corrosion resistance, making ceramic products lasting for a long time. It is indispensable in the production of daily porcelain and artistic porcelain.
Furthermore, in the metallurgical industry, it also has its own shadow. Sodium hexafluorozirconate can be used as a modifier for aluminum alloys, optimizing the structure of aluminum alloys, and greatly improving their strength and toughness. The aluminum alloys treated with it have outstanding properties and are widely used in aerospace, automobile manufacturing and other fields that require strict material properties.
In addition, in the field of chemical analysis, sodium hexafluorozirconate also plays a key role. Due to its unique chemical properties, it can be used as an analytical reagent for the determination and separation of specific elements, enabling researchers to accurately analyze the composition of substances and promoting the progress of chemical research.
In the electronics industry, it can also be seen. The manufacture of some electronic components requires the use of sodium hexafluorozirconate to improve material properties, ensure the stable operation of electronic equipment, and contribute to the development of modern science and technology.
What are the physical properties of Sodium Zirconium (4 +) Fluoride (2:1:6)
Sodium zirconium (IV) fluoride (2:1:6), its scientific name is sodium hexafluorozirconate, and its chemical formula is Na ² ZrF. The properties of this substance are usually white crystalline powder, which is dense and heavy, about 3.68 g/cm ³. The melting point is very high, reaching 996 ° C. It melts into a liquid at high temperature, and returns to a solid state after cooling.
Its solubility varies, and it is soluble in water. After dissolving, ions disperse in water and form ionic states. It can also dissolve in acids, such as hydrochloric acid, sulfuric acid, etc., and reacts with acids or chemically. However, in alkali, it is difficult to dissolve and chemically stabilizes.
Its stability is quite good, and it is not easy to react with surrounding objects at room temperature and pressure. In case of strong acid and alkali, the environment changes drastically, or triggers a reaction. And in high temperature conditions, or with some metals, such as aluminum, magnesium, etc., there is a chemical interaction to form new compounds.
The conductivity of sodium hexafluorozirconate varies depending on the state of dissolution. In aqueous solution, it can conduct electricity due to the presence of ions; in solid state, the ions are difficult to move and the conductivity is weak. This substance is widely used. In the aluminum electrolysis industry, it is often used as a flux to reduce the melting point of alumina and reduce energy consumption. In the ceramic industry, it is used as a glaze additive to increase the color and hardness of ceramics.
Is Sodium Zirconium (4 +) Fluoride (2:1:6) Chemically Stable?
Sodium zirconium (IV) fluoride (2:1:6), its scientific name is sodium hexafluorozirconate, and the chemical formula is $Na_2ZrF_6 $. The chemical properties of this substance are quite stable.
Investigate the reason, from the structural point of view, $Na_2ZrF_6 $internal ionic bond force is strong. Sodium ion ($Na ^ + $) and hexafluorozirconate ion ($ZrF_6 ^ {2 -} $) attract each other to form a stable lattice structure. The fluorine atom is extremely electronegative, and the covalent bond formed with the zirconium atom is firm. The hexafluorozirconate ion has a stable structure and is not easy to deform or dissociate.
From the perspective of chemical activity, $Na_2ZrF_6 $is difficult to react with common substances such as water and oxygen at room temperature and Although water is a polar molecule, it is difficult to break its ionic bonds and internal covalent bonds of hexafluorozirconate. Oxygen oxidation is not enough to oxidize the elements. Even under heating conditions, the decomposition temperature is quite high, and it usually takes a higher temperature to decompose gradually, which shows its chemical stability.
Sodium Zirconium (4 +) Fluoride (2:1:6)
To prepare sodium zirconium (IV) fluoride (2:1:6), the method is as follows.
Prepare the required materials first. Sodium chloride is commonly used for sodium sources, and it is easy and pure to obtain. The zirconium source is zirconium oxychloride, which is suitable for this system. The fluorine source is mostly hydrofluoric acid, which has strong activity and good effect.
In a suitable container, hold an appropriate amount of water. The water temperature should be stable, about room temperature. First dissolve the zirconium oxychloride in water, stir to promote the solution, until the solution is clear. Slowly add hydrofluoric acid, stir while adding, to prevent overreaction. At this time, fluoride ions and zirconium ions are complexed to produce fluorozirconic acid.
Then, weigh the sodium chloride according to the amount and gradually add it to the above mixture. Stir continuously to make the sodium ions and fluorozirconate ions fully interact. In this process, temperature control and stirring are key to ensure uniform reaction.
After the reaction is completed, let it stand to precipitate, and obtain a mixed solution containing sodium zirconium (IV) fluoride. By filtration method, divide solid and liquid. The filtered solid is rinsed several times with pure water to remove impurities. Then dry at low temperature to obtain pure sodium zirconium (IV) fluoride (2:1:6). The drying temperature should not be high to avoid product decomposition. The whole preparation requires strict adherence to operating specifications to ensure safety and product quality.
