Strong Ceramic Composition Technology    

A functional material for electronics, computers and information technology, biotechnology and medical electronics.

Overview

A ceramic composition process for manufacturing a strong ceramic body that after being formed into the preferred shape and size can be fired without any shrinkage or distortion.

Primary Application of the Technology

For shaping a multilayered electronic device, every layer can be a different composition, taking on a comparable co-efficient thermal expansion, and consequently having different electrical properties.

Other Potential Applications

Inkjet printing - a proven technology useful in the creation of high speed ink jet heads. As the number of jets increases the temperature of the head increases to the point where the plastic becomes distorted destroying ink placement tolerances. Using this technology one can produce ceramic heads or insert which can be placed into a plastic jet head, these can withstand high temperatures greatly increasing the number of jets per head often needed for high printing speed commercial scale cartridges.

The ceramic can be molded or machined in the green state and upon firing the ceramic will not shrink appreciably thereby preserving the finished dimensions of the device. By this means very complex 3 dimensional shapes can be easily produced in ceramic articles.

Patent Summary

U.S. Patent Classes & Classifications Covered in this Patent:

Class 501: Compositions: Ceramic

This is the generic class for: Glass compositions and compositions for making glass, i.e., glass batch compositions, devitrified glass-ceramic compositions and processes for producing such compositions. These compositions may be regarded as thermoplastic compositions. Refractory compositions comprising primarily earthy, inorganic materials, and/or elemental carbon. Fired clay containing compositions in the nature of porcelain, earthenware, and similar materials. These compositions may be regarded as thermosetting compositions

Subclass 19: Free metal as other material
Subclass 32: Glass and material other than glass (e.g., crystal glass, opal glass, etc.)

Class 264: Plastic And Nonmetallic Article Shaping Or Treating: Processes

Processes for molding, casting, or shaping of nonmetallic materials to produce articles. Liquid or melt comminuting of materials other than glass or metal. Uniting or compacting of bulk or randomly assembled particles. Furnace Lining or repair. Melt shaping in the absence of a mold or shaping surface, e.g., spheroidizing of particles. Working or treatment of nonmetallic materials not otherwise provided for.

Subclass 656: Including nonsintering burn-off, volatilization, or melting of binder
Subclass 657: Of synthetic resin binder
Subclass 660: With drying of shaped article or preform using nonsintering heat
Subclass 667: Including specified molding pressure or controlling of molding pressure (e.g., cold isostatic pressing, hydrostatic pressure, etc.)

Class 419: Powder Metallurgy Processes

This is the generic class for producing metals, alloys or metal containing compositions in a solid or compact state from powdered or particulate material with or without heating.

Subclass 19: Oxide containing

Class 428: Stock Material Or Miscellaneous Articles

This is the residual class for: 1. Stock material in the form of a structurally defined web, sheet, rod, strand, fiber, filament, cell, flake, particle not provided elsewhere. 2. Stock material in the form of a web, sheet, mass or layer which consists of or contains a structurally defined constituent or element. 3. A nonstructural laminate defined merely in terms of the composition of one or more layers. 4. An article of manufacture or an intermediate-article not provided for elsewhere. 5. A process for applying an impregnating material to a naturally solid product such as a wood beam, a sheet of leather or a stone, or for applying a coating to a base, and which process includes no significant method step.

Subclass 432: Next to metal or compound thereof
Subclass 433: Alloy or free metal
Subclass 688: Of inorganic material

Class 65: Glass Manufacturing

(1) processes and/or apparatus for making stock or articles of those ceramic masses, which generally include a "glass former" or an oxide which approaches glass forming properties, in their composition and which are formed by fusion of raw materials (generally mixtures, most of which are of an earthy nature - as distinguished from metallic, organic, etc., - silicon, silica, and slag are included) at ordinary high furnace temperatures, by working (molding, shaping, etc.) of the mass after being melted or changed to a plastic or softened state by heating; and (2) processes and/or apparatus for treating stock or articles made

Subclass 17.3: With shaping of particulate material and subsequent fusing of particles
