Flammability inorganic compound

Inert Gas Dilution. Inert gas dilution involves the use of additives that produce large volumes of noncombustible gases when the polymer is decomposed. These gases dilute the oxygen supply to the flame or dilute the fuel concentration below the flammability limit. Metal hydroxides, metal carbonates, and some nitrogen-producing compounds function in this way as flame retardants (see Flame retardants, antimony and other inorganic compounds). 

Organic compounds contain covalent bonds. In general, compared to inorganic compounds organic compounds have low melting and boiling points, tend to be flammable, have relatively low densities, do not dissolve readily in water, and are primarily nonelectrolytes. 

The nature and composition of the volatile products, and the quantity of the char, determine the flammability of the cellulosic material and the rate of combustion or propagation of the fire, which is highly sensitive to the effect of the physical and environmental conditions prevailing, as well as to the chemical factors, such as the minor components and inorganic compounds present.

Plastics are generally organic polymers of high molecular mass. They are usually synthetic and derived from petrochemicals. Also they are malleable and can be molded into solid objects of various shapes. Most plastics contain other organic or inorganic compounds that are blended in. These include fillers which improve performance and may reduce production costs. One such additive might be a fire retardant to lower the flammability of the material. Another could be a colorant to enhance its appearance. Figure 3 displays a plastic vase [13]. 

Binary room-temperature ionic liquid (RTIL)-based electrolytes have attracted significant attention because of their negligible vapor pressure good thermal and electrochemical stability in the range of 5.3 V [83] good dissolution properties with many organic and inorganic compounds and lithium salts and low flammability [84]. 

Many ILs exhibit interesting properties. Most of them are thermally stable up to high temperatures, they are non-flammable and their vapour pressures are extremely low. Therefore ILs can normally not be distilled making their purifieation more complicated. They are good solvents for both organic and inorganic compounds and there is some hope that in several industrial proeesses ILs can substitute for toxic solvents like benzene, earbon disulfide etc. ... 

Inorganic boron compounds are generally good fire retardants (59). Boric acid, alone or in mixtures with sodium borates, is particularly effective in reducing the flammability of cellulosic materials. Applications include treatment of wood products, cellulose insulation, and cotton batting used in mattresses (see Flame retardants).
