High Strength Cordierite Ceramic

View page
US Patent:
42683114, May 19, 1981
Filed:
Nov 1, 1979
Appl. No.:
6/090470
Inventors:
Dennis M. VerDow - Lancaster OH
Assignee:
Anchor Hocking Corporation - Lancaster OH
International Classification:
C04B 3324
US Classification:
106 45
Abstract:
A ceramic body having the oxide composition, SiO. sub. 2 : 33-46 wt. % Al. sub. 2 O. sub. 3 : 37-57 wt. % MgO: 5. 5-15 wt. % ZnO: 0. 4-1. 7 wt. % Na. sub. 2 O+K. sub. 2 O: 1. 0-3. 0 wt. % ZrO. sub. 2 : 0-5 wt. % The sum of these oxides (including ZrO. sub. 2, if present) should preferably be at least 97% of the total. The remainder of the composition may comprise those ingredients such as CaO, Fe. sub. 2 O. sub. 3 and/or TiO. sub. 2, which are normally present in conventional ceramic batch raw materials. Essentially no Li. sub. 2 O should be present. The fired body, in which cordierite is the perdominant crystal phase, has a modulus of rupture greater than 10,000 psi and often higher than 14,000 psi, and is suitable for freezer-to-oven utensils and for dinnerware. It is glazable with a wide range of glazes including non-Li. sub. 2 O containing glazes.

Method Of Making Glassware Having A Handcrafted Appearance

US Patent:
39868559, Oct 19, 1976
Filed:
Feb 13, 1975
Appl. No.:
5/549708
Inventors:
Charles M. Smith - Lancaster OH
Dennis M. VerDow - Lancaster OH
Assignee:
Anchor Hocking Corporation - Lancaster OH
International Classification:
C03C 304
US Classification:
65 22
Abstract:
Glassware having small bubbles or blisters that impart a handcrafted appearance to it is made by metering specially formed decomposable granules into a soda-lime glass melt at the feeder of a glass forming machine. The granules are made by coating or wetting an alkali metal nitrate with sodium silicate aqueous solution. They decompose in the melt, but the water glass coating slows the decomposition rate such that the resulting gas inclusions cannot escape from the melt before it has been formed or set in a desired shape in the forming machine.
