The application discloses and claims an oxidation resistant, continuous-fiber-reinforced ceramic composition, durable at temperatures above 1000&#xb0; C., and capable of taking on any arbitrary near net shape formed without machining and tooling. The composition of the invention comprises a fine grained ceramic matrix which in turn comprises a mixture of a ZrBphase and a SiC phase with the matrix being reinforced with SiC or C or an oxide fiber, resulting in a fine grained ZrB&#x2014;SiC matrix with domain sizes &#x2266;0.5 &#x3bc;m. The ZrBphase of the invention is capable of forming small microcrystalline domains &#x2266;0.5 &#x3bc;m upon heat treatment. The composition the invention also comprises a fiber reinforced composite with a high degree of filling and densification of its preform resulting in a composition containing a low level of porosity and high fiber volume fraction.

Continuous-fiber-reinforced amorphous ceramic composition

A method for removing dissolved solids, particularly salts, from water. An apparatus for performing the inventive method is disclosed. The aqueous solution to be treated, for example sea water, is atomized using special non-pneumatic nozzles, and sprayed into an evaporation chamber through which air, heated by waste heat, is blown. The micro-droplets undergo rapid evaporation in the chamber, resulting in the separation of the salt solids from the vapor phase of the water. The mixture of suspended solids and water vapor is filtered to remove and collect the salts, and the water vapor is condensed to collect the salt-free water.
