Abstract
A ceramic composite is provided comprising ceramic fibers and microparticles bound together as a porous matrix with a ceramic binder. The ceramic composite is particularly useful for transporting cryogenic fluids.
Claims1
A heat pipe comprising a core of porous ceramic composite, said core accommodating a central channel extending along the longitudinal axis of said pipe, and a plurality auxiliary channels radially displaced about said central channel, said auxiliary channels extending along the longitudinal axis of said pipe;
- a ceramic matrix laminate annularly surrounding said core;
- and a sealing coating at least annularly surrounding said laminate;
- wherein said porous ceramic composite comprising about 0-99 wt % ceramic fibers and about 1-100 wt % microparticles bound together as a porous matrix with a ceramic binder.
