==Combustion of non-flammables==
The higher pressure and concentration of {{chem|O|2}} in the bomb system can render combustible some compounds that are not normally flammable. Some substances do not combust completely, making the calculations harder as the remaining mass has to be taken into consideration, making the possible error considerably larger and compromising the data.

When working with compounds that are not as flammable (that might not combust completely) one solution would be to mix the compound with some flammable compounds with a known heat of combustion and make a pallet with the mixture. Once the {{tmath|C_\text{v} }} of the bomb is known, the heat of combustion of the flammable compound ({{mvar|C<sub>''FC''</sub>}}), of the wire ({{mvar|C<sub>''W''</sub>}}) and the masses ({{mvar|m<sub>''FC''</sub>}} and {{mvar|m<sub>''W''</sub>}}), and the temperature change (Δ''T''), the heat of combustion of the less flammable compound ({{mvar|C<sub>''LFC''</sub>}}) can be calculated with:
