Abstract
In an approach to synthesizing transparent ceramic windows, a powder is synthesized. A green body is fabricated from the powder. The green body is densified.
Claims20
A process to synthesize transparent ceramic windows, the process comprising:
- synthesizing a powder;
- fabricating a green body from the powder;
- and
- densifying the green body.
1 more element
A process to synthesize transparent ceramic windows, the process comprising:
- condensing a precursor solution to form a gel;
- reducing the gel by evaporation;
- pyrolyzing the gel to complete crystallization of the gel into a powder;
- dispersing the powder in a colloidal stabilizer using ultrasonic dispersion;
- draining a dispersing media from the colloidal stabilizer;
- removing volatile organic compounds from the colloidal stabilizer;
- and
- filtering the colloidal stabilizer to remove foreign particles to yield a green body;
- loading the green body into an electrically conducting die;
- and
- sintering the powder under a uniaxial pressure.
