Abstract
A catalyst-containing material includes a refractory matrix and particles of one or more catalytic metal elements or catalytic oxides. The particles are dispersed through, and embedded in, the refractory matrix.
Claims22
A catalyst-containing material comprising:
- a refractory matrix;
- and
- particles of one or more catalytic metal elements or catalytic oxides, the particles being dispersed through, and embedded in, the refractory matrix.
A method of fabricating a catalyst-containing material, the method comprising:
- providing a mixture of matrix particles and particles of one or more catalytic metal elements or catalytic oxides;
- combining the mixture with at least a binder to produce one or more green state bodies;
- thermally treating the one or more green state bodies, the thermal treatment causing a sintering of the matrix particles to produce a refractory matrix with the particles of the one or more catalytic metal elements or the catalytic oxides dispersed through, and embedded in, the refractory matrix.
A thruster comprising:
- a combustion chamber;
- an injector for providing propellant into the combustion chamber;
- an exit for discharging decomposition products from the combustion chamber;
- and
- a catalyst-containing material in the combustion chamber for catalyzing reaction of the propellant, the ceramic matrix catalyst composite including
- a refractory matrix;
- and
- particles of one or more catalytic metal elements or catalytic oxides embedded in, and dispersed through, the refractory matrix.
