Main distinction – salt Fluoride vs Calcium Fluoride
Fluorides are chemical compounds containing fluoride ion (F–). Sodium fluoride and also calcium fluoride space two such compounds. Salt fluoride (NaF) is written of salt cation and fluoride anion. That is a medication supplied to stop tooth degeneration caused by the low fluoride uptake. That is likewise used to treat kids in areas where fluoride contents in drink water is low. Calcium fluoride is composed of calcium cation and also fluoride anion. It is present in the type of a naturally occurring mineral dubbed fluorite. The key difference between sodium fluoride and also calcium fluoride is the sodium fluoride consists of one salt cation in association through one fluoride anion whereas calcium fluoride includes one calcium cation in association v two fluoride anions.

What is salt Fluoride
Sodium fluoride is an not natural salt written of sodium cations and also fluoride anions. The chemical formula of salt fluoride is NaF. The molar fixed of this link is 41.99 g/mol. It is a white come greenish hard compound that is odorless.
The melting suggest of salt fluoride is 993 °C, and also the boiling suggest is 1,704 °C. Sodium fluoride is one ionic compound. This link exists in a cubic, crystalline structure that is comparable to the structure of salt chloride; NaCl.
Figure 1: sodium Fluoride Ionic Structure
Sodium fluoride occurs in nature in the kind of villiaumite, which is a rare mineral. However, that is do industrially because that its applications. It is developed by the neutralization that hydrofluoric acid (HF) using a perfect base. This involves the reaction between HF and also NaOH. HF is acquired as a byproduct that the manufacturing of phosphoric mountain from fluorophosphates through wet process.
HF + NaOH → NaF + H2O
Sodium fluoride is composed of salt cation and fluoride anion. That is offered as a medication to prevent tooth degeneration caused through the low fluoride uptake. That is used also to treat youngsters in locations where fluoride contents in drink water is low. NF also has countless applications in chemistry for synthesis and extractive metallurgy. In addition, that is provided in organic synthetic reactions, as a clean agent and also as a poison for plant-feeding insects.
What is Calcium Fluoride
Calcium fluoride is an inorganic salt created of calcium cation and fluoride anions. The chemical formula of calcium fluoride is CaF2, and also the molar fixed is 78.07g/mol. It shows up as a white crystalline solid. However, the single crystals of Calcium fluoride space transparent.

The melting suggest of calcium fluoride is 1,418 °C, and the boiling allude is 2,533 °C. Calcium fluoride occurs naturally as fluorite mineral. It has a deep color due to the presence of different impurities. It is abundant but is largely used because that the production of HF acid. High purity Calcium fluoride is industrially created by treating calcium lead carbonate (CaCO3) through hydrofluoric mountain (HF).
CaCO3 + 2HF → CaF2 + CO2 + H2O
As one application, naturally occurring fluorite is provided as a precursor because that the manufacturing of HF acid. This production process involves calcium fluoride reaction with sulfuric acid, which returns calcium sulfate (CaSO4) solid and HF gas. Calcium fluoride is provided for the production of optical contents such together windows, lenses, etc.
Difference between Sodium Fluoride and also Calcium Fluoride
Sodium Fluoride: salt fluoride is an not natural salt composed of a salt cation and also a fluoride anion.
Calcium Fluoride: Calcium fluoride is an not natural salt composed of a calcium cation and fluoride anions.
Sodium Fluoride: The chemical formula of salt fluoride is NaF.
Calcium Fluoride: The chemistry formula that calcium fluoride is CaF2.
Sodium Fluoride: The molar fixed of salt fluoride is 41.99 g/mol.
Calcium Fluoride: The molar mass of calcium fluoride is 78.07g/mol.
Melting point and boil Point
Sodium Fluoride: The melting suggest of sodium fluoride is 993 °C, and the boiling suggest is 1,704 °C.
Calcium Fluoride: The melting suggest of calcium fluoride is 1,418 °C, and also the boiling point is 2,533 °C.
Sodium Fluoride: salt fluoride wake up in nature in the kind of villiaumite, i beg your pardon is a rarely mineral.
Calcium Fluoride: Calcium fluoride occurs naturally as fluorite mineral.
Sodium Fluoride: sodium fluoride is largely used as a medication for tooth decay.
Calcium Fluoride: Calcium fluoride is mostly used together a precursor to develop HF acid.
Sodium Fluoride: sodium fluoride is developed by the reaction in between HF and also NaOH.
Calcium Fluoride: Calcium fluoride is industrially produced by dealing with calcium lead carbonate (CaCO3) through hydrofluoric mountain (HF).
Sodium fluoride and also calcium fluoride are fluoride salts. The main difference in between sodium fluoride and also calcium fluoride is that sodium fluoride consists of one salt cation in association v one fluoride anion conversely, calcium fluoride includes one calcium cation in association with two fluoride anions.
