Which term is used to describe materials that can stimulate or support combustion?

The term that describes materials that can stimulate or support combustion is "oxidizing materials." These substances provide the oxygen necessary for combustion to occur and can significantly enhance the fire's intensity. Oxidizing agents, which often include chemicals such as hydrogen peroxide, nitrates, and chlorates, are not flammable themselves but can accelerate the burning of other materials by supplying oxygen, thus creating a more conducive environment for combustion.

In contrast, while flammable materials can easily catch fire, they are not specifically recognized for their role in supporting or stimulating combustion in the same way that oxidizing materials do. Similarly, combustible materials are substances that can catch fire and burn, but again, they do not inherently provide the essential oxygen needed for combustion. Inert materials are those that do not support combustion at all, as they lack the necessary reactive components to sustain a fire.
