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.

The invention relates to the use of a printing sol as construction material in an additive manufacturing process for producing a 3-dim article, the printing sol comprising solvent(s), nano-sized crystalline zirconia particles in an amount from 2 to 25 vol.-% with respect to the volume of the sol, the average primary particle size of the nano-sized crystalline zirconia particles being in a range up to 50 nm, a first monomer being a polymerizable surface modification agent represented by formula A-B, with A being capable of attaching to the surface of the nano-sized crystalline zirconia particles and B being a radiation curable group, optionally a second monomer, the second monomer comprising at least one radiation curable moiety but no acidic or silane group(s), photo initiator(s). The invention also relates to a ceramic article obtainable according to such a process.

Metal oxide particles, such as molded particles, as well as methods of making and articles containing the same. The particles can contain at least 70 mol percent ZrO, and can be made by a molding process.

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.

Aerogel, calcined articles, and crystalline articles comprising ZrO. Exemplary uses of the crystalline metal oxide articles include dental articles (e.g., restoratives, replacements, inlays, onlays, veneers, full and partial crowns, bridges, implants, implant abutments, copings, anterior fillings, posterior fillings, and cavity liner, and bridge frameworks) and orthodontic appliances (e.g., brackets, buccal tubes, cleats, and buttons).

Zirconia-based particles, sols containing the zirconia-based particles, methods of making the sols and the zirconia-based particles, composites containing the zirconia-based particles in an organic matrix, and sintered bodies prepared from the zirconia-based particles are described. The zirconia-based particles are crystalline, have a primary particles size no greater than 100 nanometers, and are doped with a lanthanide element or with both a lanthanide element and yttrium.

Vacuum insulated glass units having layered pillars. The glass units include two glass panes and an edge seal between the glass panes with a substantial vacuum gap between them. A plurality of pillars are located between the glass panes as spacers to maintain the vacuum gap. The pillars have a sintered ceramic, alpha alumina, or zirconia body with a tapered sidewall and a functional layer on a surface of the body.

Sintered bodies containing zirconia-based ceramic materials and partially sintered bodies that are intermediates in the preparation of the sintered bodies are described. The zirconia-based ceramic material is doped with lanthanum and yttrium. The grain size of the zirconia-based ceramic material can be controlled by the addition of lanthanum. The crystalline phase of the zirconia-based ceramic material can be influenced by the addition of yttrium.
