  • Publication number: 20240326288
    Abstract: The present disclosure provides a transparent alumina-based plate, and a hot-pressing method to make the transparent alumina-based plate from platelet alumina. Alumina powder with a platelet morphology was hot-pressed to transparency with pre-load pressures of about 0-8 MPa, maximum temperatures of about 1750-1825° C., maximum pressures of about 2.5-80 MPa, and isothermal hold times of 1-7 hours. A novel alumina-based plate has been prepared, wherein the plate has a thickness of 2-5 mm, an in-line transmission of at least 60-75% for a light with a wavelength range of 645-2500 nm, an in-line transmission variance of <15% over the wavelength range of 645-2500 nm, and a relative density of 99.00-99.95%.

  • Publication number: 20240067575
    Abstract: Methods of manufacturing carbon/carbon preforms and carbon/carbon composites formed therefrom. Such a method includes extruding a polymer composite material using an extrusion deposition additive manufacturing process to form a preform, and heating the preform via pyrolysis to form the carbon/carbon composite.

  • Publication number: 20170129135
    Abstract: A method for ambient temperature injection molding of ceramic bodies, including combining ceramic powder, water, and dispersant to yield a first admixture, combining water and water soluble polymer to yield a second admixture, combining the first and second admixture to yield a homogeneous slurry, flowing the homogeneous slurry into a mold to yield a molded green body, and removing the green body from the mold, all of which are performed at room temperature. The slurry exhibits yield psuedoplastic flow characteristics and contains more than 50 weight percent ceramic powder and less than 5 weight percent water soluble polymer.
