The present disclosure relates to a fire extinguishing composition containing saccharide and a saccharide derivative, comprising a saccharide derivative, a saccharide material and an auxiliary fire extinguishing agent, whose mass percentages are respectively: saccharide derivative 30%-60%, saccharide material 10%-40%, and auxiliary fire extinguishing agent 10%-30%. The fire extinguishing composition uses a pyrotechnic agent as a heat source and a power source, is heated and decomposed or reacts by using the heat of burning of the pyrotechnic agent, to generate a fire extinguishing material to be sprayed together with the fireworks agent, thereby achieving the fire extinguishing purpose. The fire extinguishing composition of the present disclosure uses a saccharide derivative and a saccharide material as primary ingredients, uses a pyrotechnic agent as a heat source and a power source, and is easily decomposed after being heated to generate non-toxic and harmless gas. The environment is not polluted after the ejection, the effective utilization rate of components is high, and the material obtained through decomposition can also extinguish fire, so as to generate a synergistic action on the pyrotechnic agent, thereby improving the fire extinguishing performance of the whole fire extinguishing composition.

A metal-carbonyl-containing fire extinguishing composition comprises metal carbonyl complexes. The fire extinguishing composition uses a pyrotechnic agent as a heat source and a power source. A high temperature in combustion of the pyrotechnic agent enables the fire extinguishing composition to decompose or react under heat; produced fire extinguishing substances are sprayed out together with the pyrotechnic agent, thereby achieving a fire extinguishing objective. In the fire extinguishing composition, by selecting preferable components and optimizing contents of the components, an optimum formula of the fire extinguishing composition is determined, thereby greatly improving the efficacy of the fire extinguishing composition. In addition, efficacies of the components in the fire extinguishing composition are fully utilized, which improves an effective utilization rate of the fire extinguishing composition.

A fire-extinguishing material composition contains: a fire-extinguishing agent containing at least one salt of a deliquescent organic salt or inorganic salt; and a compound having an acid anhydride group. A fire-extinguishing material according to the present disclosure is formed from the fire-extinguishing material composition.
