Patent number: 11884550Abstract: Shaped gel articles that are formed within a mold cavity and that retain the size and shape of the mold cavity upon removal from the mold cavity, sintered articles prepared from the shaped gel articles, and methods of making the sintered articles are provided. The shaped gel articles are formed from a casting sol that contains colloidal silica particles that are treated with a surface modification composition that includes a silane surface modification agent having a radically polymerizable group. The sintered article has a shape identical to the mold cavity (except in regions where the mold cavity was overfilled) and to the shaped gel article but reduced in size proportional to the amount of isotropic shrinkage.Type: GrantFiled: August 16, 2017Date of Patent: January 30, 2024Assignee: 3M Innovative Properties CompanyInventors: Kathleen M. Humpal, Melissa A. Lackey, Brant U. Kolb, Paul D. Pennington, Mark J. Hendrickson

Publication number: 20220380260Abstract: The present disclosure provides a method of making a ceramic article. The method includes (a) obtaining a photopolymerizable slurry or sol including a plurality of ceramic particles distributed in the photopolymerizable slurry or sol and (b) selectively polymerizing the photopolymerizable slurry or sol using actinic radiation and continuous movement of a build substrate through the photopolymerizable slurry or sol to form a gelled article. The method also includes (c) extracting solvent from the gelled article to form an aerogel article or a xerogel article; (d) heat treating the aerogel article or the xerogel article to form a porous ceramic article; and (e) sintering the porous ceramic article to form a sintered ceramic article. The sintered ceramic article exhibits a particular density. Further, additive manufactured ceramic articles are provided that exhibit a particular density, opacity, or both.Type: ApplicationFiled: August 3, 2020Publication date: December 1, 2022Inventors: Amy T. Shah, James D. Hansen, David B. Stegall, Alexander J. Huffman, Gareth A. Hughes, Melissa A. Lackey, Kathleen M. Humpal, Andreas M. Geldmacher, Kristen F. Keller

Patent number: 10436984Abstract: An optical network comprises a fiber distribution cable and a terminal assembly. The terminal assembly receives a plurality of optical fibers from the fiber distribution cable and distributes one or more individual fibers to one or more single fiber bare-fiber holders that hold and protect each single fiber prepared and configured for splicing via an individual splicing element. The splicing element includes an alignment mechanism having a base plate and a clamp plate. At least one of the base plate and clamp plate is formed from a silica material and at least one of the base plate and clamp plate includes an alignment groove or channel configured to receive the first and second optical fibers in an end-to-end manner. The splice element also comprises an optical adhesive disposed in at least a portion of the alignment groove, wherein the optical adhesive is curable via actinic radiation.Type: GrantFiled: September 5, 2017Date of Patent: October 8, 2019Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: William J.
