Preparation of sintering resistant hexaaluminates, AAl11O18, wherein A is an alka-line earth or rare earth metal, and more particularly lanthanum, by a combination of sol-gel and microemulsion techniques using a water soluble salt of A, and a method of forming spherical pellets thereof are disclosed.

Sintering resistant catalyst material and a method for the preparation thereof

A method of preparing spherical pellets from a slurry comprising a ceramic powder, a solvent, and any desired additives, by means of a drop-generating orifice to which said slurry is fed is described, wherein the drops are released from said orifice by means of a relative flow of a liquid medium which is a poor solvent for the solvent of the slurry, formed into spherical bodies in said liquid medium by means of the action of surface tension, and thereafter treated for consolidation. More specifically, the present invention relates to the preparation of pellets of a catalyst or catalyst support material, suitable for use in high temperature conditions.

Method of preparing granules

The present invention relates to a reactor for the decomposition of ammonium dinitramide-based liquid monopropellants into hot, combustible gases for combustion in a combustion chamber, and more particularly a rocket engine or thruster comprising such reactor and a combustion chamber. The invention also relates to a process for the decompostion of ammonium dinitramide-based liquid monopropellants.
