  • Thruster propellants
    Patent number: 12692206
    Abstract: The present invention relates to thruster propellants, processes of making thruster propellants and space vehicles comprising thrusters that employ such propellants. The disclosed thruster propellants are advantageous because they possess higher mass-to-charge ratios. Furthermore, when compared to previous thruster propellants they have a higher conductivity and/or a higher density. Thus, when used in a thruster, such propellants can generate equal or higher thrust than previous thruster propellants.
