The chemical composition of basic thermite used in college chemistry labs primarily consists of aluminum powder and iron(III) oxide (Fe2O3). This mixture typically appears as a white or grey powder. The reaction between these components produces molten iron and aluminum oxide, demonstrating an exothermic reaction that is commonly utilized in demonstrations and experiments. The standard ratio for this thermite reaction is approximately 3 parts iron oxide to 1 part aluminum by weight.
