Abstract: A transparent polycrystalline body having high ultraviolet transmissivity is provided. The body is preferably a sintered magnesia-alumina spinel body having a transmittance of at least 85 percent in the wavelength range from 0.4 microns to 0.8 microns and a transmittance at some wavelength in the wavelength range between about 0.2 and about 0.4 microns of at least about 86 percent and a porosity of less than about 0.001 percent. The sintered body is produced by a two-step method comprising forming a closed porosity body from a spinel powder and subjecting the closed porosity body to a hot isostatic pressure treatment. The resulting body has high transmissivity of electromagnetic radiation in the range between about 0.2 microns and about 6 microns, is resistant to abrasion or erosion, does not substantially deteriorate after exposure to ultraviolet light, and has high strength. The sintered body is useful in a variety of applications, including as a dome and window for missiles and launch tubes.

Abstract: The present invention provides an aluminum borate ceramic having a high porosity and a tightly controlled pore size distribution, while maintaining good mechanical strength. The ceramic body can be formed by decomposing boric acid-stabilized aluminum acetate to form an aluminum borate powder, and sintering the powder to form a ceramic body.

Abstract: The invention provides a hard, strong ceramic body and a ceramic raw batch and method for manufacture whereby the body, after being formed of the raw batch in the shape and size desired, can then be fired to monolithic structure without any shrinkage or distortion during the firing operation. The raw batch contains aluminum oxide, magnesium oxide, glass frit and a silicone resin, these constituents being present in a ratio such that after the firing operation the resulting monolithic body contains from about 70% to 95% by weight crystalline material and the remainder interstitial glass, the crystalline material consisting predominantly of magnesium aluminate spinel and alumina. The ceramic and method have particular utility for making dental crowns and other dental appliances where a precise fit along with high strength and wear resistance are desirable.

Abstract: STEPPED CONE DRAW BLOCK A stepped cone draw block disclosed has intermediate sheaves which each include a pair of plate-like annular sheave members with peripheral flanges between which a ceramic ring for drawing a wire is clamped. Side surfaces of the sheave members of each intermediate sheave face away from each other along an axis of a shaft on which the draw block is mounted and axially facing surfaces of these sheave members are bolted in engagement with each other midway between the side surfaces. One sheave member of each intermediate sheave has a central opening sized to receive and mount the sheave on the shaft with a shaft key received within a keyway of the opening to provide coupling to the shaft, while the other sheave member has an opening slightly larger than the shaft and a groove aligned with but slightly larger than the keyway so as to facilitate mounting of the sheave. In one embodiment, the ceramic ring has a round inner surface with a semicircular slot which is aligned with a complementary semicircular slot of the sheave to receive a pin that prevents rotation therebetween. In another embodiment, the ceramic ring has an inner surface with a round portion and a flat portion that engage complementary surface portions on the sheave members to prevent relative rotation therebetween. Two of the smallest sheaves are formed by a unitary ceramic member with a central opening for receiving the shaft and a keyway formed by a polyurethane plug. A single sheave can alternately be used to replace the ceramic member and includes a pair of sheave members with a ceramic ring adhesively bonded therebetween. Another larger sheave also has a pair of sheave members with a ceramic ring adhesively bonded therebetween. The two largest sheaves of the draw block each have sheave members bolted to each other to clamp an associated ceramic ring between peripheral flanges thereof and the larger sheave is mounted on the smaller one to allow mounting on a shaft of a relatively short length.
