Nano-ceramics and method thereof
View Patent ↗Disclosed herein is a method to produce ceramic materials utilizing the sol-gel process. The methods enable the preparation of intimate homogeneous dispersions of materials while offering the ability to control the size of one component within another. The method also enables the preparation of materials that will densify at reduced temperature.
1. A method comprising:
dissolving one or more metal salts in a solvent or solvent matrix to form a metal salt solution;
adding one or more uniformly dispersed powdered materials to said metal salt solution to form a composite dispersion, wherein said powdered materials are selected from the group consisting of TiC and B 4 C;
adding a proton scavenger to the composite dispersion to form a gel, wherein the proton scavenger is an epoxide compound; and
drying the gel to form a composite material.
2. The method of claim 1 , further comprising washing said gel with a base.
3. The method of claim 2 , wherein said base comprises aqueous ammonia (NH 3 ).
4. The method of claim 1 , wherein said proton scavenger is propylene oxide.
