    Ammonium perchlorate is a well known oxidizer for solid rocket propellants. One commonly employed technique for changing the burning rate of a solid rocket propellant is to change the particle size of the ammonium perchlorate oxidizer. In general the burning rate increases as the average particle size of the oxidizer decreases.
