These have an unconfined burn rate of about 1.3 mm/s.
The burn rate of the propellant depends not only on the chemical make up, but also on the shape of the propellant grains.
Double-base powders burn faster than single-base powders of the same shape, though not as cleanly, and burn rate increases with nitroglycerin content.
The burn rate and hence chamber pressure and maximum thrust of model rocket motors is also tightly controlled.
Barium chromate is an oxidizing agent, making it useful as a burn rate modifier in pyrotechnic compositions.
Sorbitol, a sugar alcohol commonly used as a sweetener in food, produces a less brittle propellant with a slower burn rate.
Users of charcoal briquettes emphasize the uniformity in size, burn rate, heat creation, and quality exemplified by briquettes.
Metal oxides have been found to increase the burn rate of sugar propellants.
