Glass-ceramics and precursor glasses that are crystallizable to glass-ceramics are disclosed. The glass-ceramics of one or more embodiments include rutile, anatase, armalcolite or a combination thereof as the predominant crystalline phase. Such glasses and glass-ceramics may include compositions of, in mole %: SiOin the range from about 45 to about 75; AlOin the range from about 4 to about 25; POin the range from about 0 to about 10; MgO in the range from about 0 to about 8; RO in the range from about 0 to about 33; ZnO in the range from about 0 to about 8; ZrOin the range from about 0 to about 4; BOin the range from about 0 to about 12, and one or more nucleating agents in the range from about 0.5 to about 12. In some glass-ceramic articles, the total crystalline phase includes up to 20% by weight of the glass-ceramic article.

Ion exchangeable glass, glass ceramics and methods for making the same

Described herein are various antimicrobial soda lime glass articles that have improved resistance to discoloration when exposed to harsh conditions, including manufacturing conditions. The improved antimicrobial glass articles described herein generally include a SLG substrate that has a thickness, t; a compressive stress layer of about 0.15*t or greater; and an antimicrobial agent-containing region having an antimicrobial agent and a thickness less than the thickness of the compressive stress layer. Roughly 2 to 20 microns of the primary surfaces of the glass substrate can be removed prior to development of the compressive stress and antimicrobial agent-containing region. In some aspects, prior-annealed and tempered, or prior-annealed, SLG is employed as the substrate. In some aspects, the substrate includes tin at one surface. The improved SLG substrates experience substantially no discoloration when exposed to harsh conditions. Methods of making and using the glass articles are also described.

Tempered and colorless antimicrobial soda lime glass and methods of making and using same

A method of making an antimicrobial glass article that includes the steps: submersing the article in a strengthening bath to exchange a portion of ion-exchangeable metal ions in the glass article with a portion of ion-exchanging metal ions in the strengthening bath to form a compressive stress layer extending from the first surface to a diffusion depth in the article; removing a portion of the compressive stress layer from the first surface of the article to a first depth above the diffusion depth in the article to define a new first surface and a remaining compressive stress layer; and submersing the article in an antimicrobial bath to exchange a portion of the ion-exchangeable and the ion-exchanging metal ions in the compressive stress layer with a portion of the silver metal ions in the antimicrobial bath to impart an antimicrobial property in the article.

Glass with enhanced strength and antimicrobial properties, and method of making same

Described herein are various methods and manufacturing methods for making antimicrobial and strengthened, antimicrobial glass articles and substrates. The methods described herein generally include contacting the article with a KNO-containing molten salt bath set at about 380 C to about 460 C for about 30 minutes to about 24 hours to form a compressive stress layer that extends inward from a surface of the glass substrate to a first depth; and contacting the article comprising the compressive stress layer with a AgNO-containing molten salt bath set at about 300&#xb0; C. to about 400&#xb0; C. for about 5 minutes to about 18 hours to form an antimicrobial region that extends inward from the surface of the glass substrate to a second depth. The methods also include poisoning at least the AgNO-containing molten salt bath and, in some cases, the KNO-containing molten salt bath. Poisoning components include Naand Liions.

Methods of making antimicrobial glass articles

Comminuted pre-mixtures for technical ceramics production, and ceramic bodies made therefrom, the comminuted pre-mixtures being comprised of cellulosic components and alumina source components and the bodies being produced by compounding the comminuted pre-mixtures with powdered inorganic components into batch mixtures, adding liquids to the batch mixtures to form plastic batches, forming the plastic batches into shaped bodies, and heating the shaped bodies to form the ceramic bodies.

Compositions and methods for making low thermal expansion ceramic bodies

Provided herein is a method for producing glass-ceramic sheets. The method includes texturing at least one surface of a first glass sheet, and stacking the first glass sheet and a second glass sheet. The first glass sheet and the second glass sheet are stacked so that the textured surface of the first glass sheet contacts a surface of the second glass sheet. The first and second glass sheets are cerammed. After cooling, the cerammed first and second glass sheets are separated. Also provided is a pre-form for producing glass-ceramic sheets. The pre-form includes a first glass sheet having a textured surface, and a second glass sheet contacting the first glass sheet. The textured surface of the first glass sheet is in contact with a surface of the second glass sheet.

Method for reducing glass-ceramic surface adhesion, and pre-form for the same

A method for producing high porosity ceramic substrate articles including a fire-cycle or firing schedule that includes fast-heating rates, as defined herein.

Method for pore size distribution control in a fired ceramic article

Disclosed are synthetic silica glass body with a birefringence pattern having low fast axis direction randomness factor and glass reflow process. The glass reflow process comprises steps of: providing a glass tube having a notch; and thermally reflowing the glass tube to form a glass plate. The process can be advantageously used to produce fused silica glass plate without observable striae when viewed in the direction of optical axis. Also disclosed are optical members comprising the fused silica glass body and a process for reflowing glass cylinders.

Thermal reflow of glass and fused silica body

Disclosed is a method for treating glass and crystalline inorganic materials whereby metal contamination during such process is inhibited. Such process includes treating the material in the presence of a purifying atmosphere comprising a cleansing gas. The process is especially advantageous for treating high purity fused silica glass for use in advanced lithographic devices.
