With the rapid development of industry, a larger and larger range of Chemicals are invented and widely used in the production like Fluorine Chemicals.

Animals that eat fluorine-containing plants may accumulate large amounts of fluorine in their bodies. Fluorine primarily accumulates in bones. Consequently, animals that are exposed to high concentrations of fluorine suffer from dental decay and bone degradation. Too much fluorine can also cause the uptake of food from the paunch to decline and it can disturb the development of claws. Finally, it can cause low birth-weights.

Just like Fluorine Chemicals Lithium Chemicals are also commonly used. Lithium is the first of the alkalis in the periodic table. In nature it’s found like a mixture of the isotopes Li6 and Li7. It's the lightest solid metal, and is soft, silvery-white, with a low melting point and reactive. Many of its physical and chemical properties are more similar to those of the alkaline earth metals than to those of its own group. Between the most significant properties of lithium we find its high specific heat (calorific capacity), the huge temperature interval in the liquid state, high termic conductivity, low viscosity and very low density. Metallic lithium is soluble in short chain aliphatic amines, like etilamine. It's insoluble in hydrocarbons.

Lithium takes part in a huge number of reactions, with organic reactants as well as with inorganic reactants. It reacts with oxygen to form monoxide and peroxide. It’s the only alkaline metal that reacts with nitrogen at ambient temperature to produce a black nitrure. It reacts easily with hydrogen at almost 500oC (930oF) to form lithium hydride. Metallic lithium’s reaction with water is extremely vigorous. Lithium reacts directly with the carbon to produce the carbure. It binds easily with halogens and forms halogenures with light emission. Although it doesn’t react with parafinic hydrocarbons, it experiments addition reactions with alquenes substituted by arile and diene groups. It also reacts with acetylenic compounds, forming lithium acetylures, which are important in vitamin A synthesis.

The main lithium compound is the lithium hydroxide. It's a white powder; the manufactured material is monohydrate lithium hydroxide. The carbonate can be used in the pottery industry and in medicine as an antidepressant. The bromine and the lithium chloride both form concentrated brine, which have the property of absorbing the humidity in a wide interval of temperature; these brines are used in the manufactured air conditioning systems.

The main industrial use of lithium is in lithium stearatum form, as lubricant grease's thickener. Other important applications of lithium compounds are in pottery, specifically in porcelain glaze; as an additive to extend the life and performance of alkaline storage batteries and in autogenous welding and brass welding.

Except for the kinds metioned above, there are other chemicals especially for Electronic Grade Chemicals like Alumina Chemicals.
