A curable slurry for forming ceramic microstructures on a substrate using a mold. The slurry is a mixture of a ceramic powder, a fugitive binder, and a diluent. The ceramic powder has a low softening temperature in a range of about 400&#xb0; C. to 600&#xb0; C. and a coefficient of thermal expansion closely matched to that of the substrate. The fugitive binder is capable of radiation curing, electron beam curing, or thermal curing. The diluent promotes release properties with the mold after curing the binder or quick and complete burn out of the binder during debinding.

The invention provides abrasive articles with optimally oriented abrasive particles and a method of making the same. The method involves contacting a substrate with the contact and mating surfaces of tools to provide an embossed substrate with perforated depressions, distributing abrasive particles within the depressions of the substrate, optimally orienting each abrasive particle in the depression containing the abrasive particle, creating a differential pressure between the top surface and the back surface of the embossed, perforated sheet wherein a lower pressure is applied to the back surface to hold the oriented abrasive particles within its depression while removing at least a major portion of abrasive particles not within the depressions from the top surface of the sheet and permanently bonding the abrasive particles in the depressions after they are optimally oriented to provide the abrasive product.

A composite material suitable for labeling a substrate. The composite material, which is preferably a ceramic composite, comprises a fired ceramic body and a layer thereon. The fired ceramic body includes a base layer that comprising a glassy phase and a refractory phase, the glassy phase being capable of wetting a substrate at an application temperature. There is sufficient color contrast between the top layer and the fired ceramic body such that a code pattern (e.g., a bar code) present (or formed) is optically discernible. Methods of making and using the same are also taught.

Multilayer, temperature resistant, composite label

Encapsulated electroluminescent phosphor particles and a method of making same. Each electroluminescent phosphor particle is encapsulated by a substantially transparent metal oxynitride coating. The coating provides the phosphor particle with reduced sensitivity to humidity accelerated decay.

Multilayer temperature resistant composite label for a cathode ray tube

A tape for heat sealing substrates comprising a self-supporting layer of glass sealant wherein the glass sealant layer comprises a low-softening point glass, a plurality of refractory particles, a dispersant, and a binder. Also described is a method for making the tape and a method of using the tape to form a sealed article.

Durable retroreflective elements

A composite bubbles comprising a silicate glass bubble or a bubble of silicate glass-ceramic having an aluminum nitride coating thereon; and a method of making the same. In another aspect, composite articles (electronic substrate materials) having the composite bubbles therein are disclosed.

Glass and glass-ceramic bubbles having an aluminum nitride coating

Machinable ceramic composites having a low dielectric constant. The composite comprises ceramic bubbles uniformly distributed throughout a ceramic matrix. These composites can be used as ceramic substrates and housings in electronic packaging, and as windows transparent to microwave and millimeter wave radiation.

Ceramic composite for electronic applications

This invention provides a composite article comprising mullite bubbles dispersed in one of a glass matrix and a glass-ceramic matrix, and a method of making the same. The composite ceramic article of the present invention is useful in applications requiring a material having a low dielectric constant, low dissipation factor, thermal expansion properties compatible with silicon, and good mechanical strength. The composite ceramic article of the present invention is particularly useful as a substrate for thick film circuits, housings for integrated circuit assemblies (i.e., covers), and materials such as gyrotron windows, that require transparency to microwaves or millimeter waves, in addition to acceptable power transmission efficiencies.
