Can Inorganic Materials Burn?

Most inorganic compounds contain ionic bonds - atoms tightly held together in contrast to organic (carbon) compounds. This allows organic compounds to react with oxygen. Salts, inorganic compounds, do not react with oxygen, hence they are non-combustable.

Is inorganic compounds flammable?

Almost all of them are flammable and have slow reactions. Inorganic compounds, on the other hand, have ionic bonds, most of them are solids with high melting points. Many of them are soluble in water but insoluble in organic solvents. Few inorganic compounds are flammable and reactions are usually fast.

Is flammable inorganic or organic?

Almost all organic liquids are considered "flammable," meaning they are capable of catching on fire and sustaining combustion (an important exception is that halogenated solvents tend to be non-flammable).
