STATEMENT OF PROBLEM Cobalt-chromium (Co-Cr) alloys have been widely used for metal-ceramic fixed prostheses and can be fabricated using conventionally cast or new computer-aided technology. However, the effect of different manufacturing methods on the metal-ceramic bond strength needs further evaluation. PURPOSE The purpose of this in vitro study was to evaluate the metal-ceramic bond streng...

CAM-LEM (Computer-Aided Manufacturing of Laminated Engineering Materials) is an SFF technology suitable for many engineering materials for which feedstock is available in sheet form; lamination and post-processing procedures are materials specific. Two methods for producing sheetstock, tapecasting and compression molding , are discussed and contrasted. Ceramic and metallic components that have ...

Bioceramics such as hydroxyapatite (HAP) have been conventionally deposited by plasma spray technique. However, due to the inherent high temperature in the plasma, deleterious effects such as evaporation, phase alteration, residual stress, debonding, and gas release etc., commonly occur in these coatings. This paper presents a novel approach to deposit bioceramic coatings at temperatures well b...

By means of thin film technology a reduction of size, cost, and power consumption of electronic circuits can be achieved. The required specifications are attained by proper design and combinations of innovative materials and manufacturing technologies. This thesis focuses on the development and fabrication of low-loss ceramic thin film devices for radio and microwave frequency applications. The...

The ceramic fiber business of Shinnikka Thermal Ceramics Corporation began in March 1984 when its Sakai Works (then Nippon Steel Chemical Sakai Works) started production of ceramic fibers after several years of preparatory arrangements. The continuous reheating furnace having all-ceramic fiber lining, high thermal efficiency and low thermal inertia that was adopted for the plate mill (put into ...

OBJECTIVES All ceramic restorations without metal have great advantages in their biocompatibility and aesthetic aspects. With the introduction of new core materials, the cores are sufficiently strong to produce long lasting all-ceramic restorations; however, the stresses in the veneering porcelain could still determine the longevity. The objective of this study was to evaluate, by finite elemen...

Dental ceramics present excellent ability to reproduce the natural teeth regarding esthetic and biomechanics. Recently, due to the advancement of ceramic technology, metal-free restorations were developed. However, the traditional metal-ceramic restorations still present the requirements of high strength, long survival in the oral environment and favorable aesthetics. In this context, it is ess...

Ceramic Bonding, Inc. (CBI) was founded in 1987 to develop technology for reliable, inexpensive, on-site conversion of heavy metal hazardous wastes to safe, useful materials, such as fine aggregate for construction applications. CBI’s principal mission is to provide equipment that can be used by industry to eliminate the need for costly and environmentally unwise disposal of toxics at Class I d...

This paper reviews recent developments in integrated fluidic mesosystems, based on low-temperature co-fired ceramic (LTCC) technology, in this laboratory and elsewhere. LTCC is shown to be an advantageous technique for integrated fluidic systems, due to its simplicity, low cost and ease of integration with other technologies and components (silicon, polymer, circuit boards. Also, the techniques...

Ceramic laser media fabricated by vacuum sintering (Ikesue et al., 1995), (Ikesue et al., 1996), and nanocrystalline (Lu et al., 2000) technology are very attractive materials because they have several remarkable advantages compared with single crystal laser materials. Ceramic samples with a large size can be easily fabricated, whereas this is extremely difficult for single crystals; multiplaye...
