Many RTD elements consist of a length of fine wire wrapped around a heat-resistant ceramic or glass core but other constructions are also used. The RTD wire is a pure material, typically platinum (Pt), nickel (Ni), or copper (Cu). The material has an accurate resistance/temperature relationship which is used to provide an indication of temperature.
The mixture was applied to the glazed ware and fired in an enameling kiln, depositing a thin film of platinum or gold. [43] Platinum produced the appearance of solid silver, and was employed for the middle class in shapes identical to those uses for silver tea services, ca. 1810–1840. Depending on the concentration of gold in the lustring ...
Lacquerware is a longstanding tradition in Japan [6] [7] and, at some point, kintsugi may have been combined with maki-e as a replacement for other ceramic repair techniques. . While the process is associated with Japanese craftsmen, the technique was also applied to ceramic pieces of other origins including China, Vietnam, and Kor
One of the earliest uses of platinum was to make crucibles. Ceramics such as alumina, zirconia, and especially magnesia will tolerate the highest temperatures. [21] However, chemical reactions with the material in the crucible must be kept in mind; the emergence of melting point-lowering eutectic systems is an especially important consideration ...
Co-fired ceramic devices are fabricated using a multilayer approach. The starting material is composite green tapes, consisting of ceramic particles mixed with polymer binders. The tapes are flexible and can be machined, for example, using cutting, milling, punching and embossing.
Franciscan Ceramics are ceramic tableware and tile products produced by Gladding, McBean & Co. in Los Angeles, California, US from 1934 to 1962, International Pipe and Ceramics (Interpace) from 1962 to 1979, and Wedgwood from 1979 to 1983. Wedgwood closed the Los Angeles plant, and moved the production of dinnerware to England in 1983.
Bioglass 45S5 is manufactured by conventional glass-making technology, using platinum or platinum alloy crucibles to avoid contamination. Contaminants would interfere with the chemical reactivity in organism. Annealing is a crucial step in forming bulk parts, due to high thermal expansion of the material.
Fracture surface of a fiber-reinforced ceramic composed of SiC fibers and SiC matrix. The fiber pull-out mechanism shown is the key to CMC properties. CMC shaft sleeves. In materials science ceramic matrix composites (CMCs) are a subgroup of composite materials and a subgroup of ceramics. They consist of ceramic fibers embedded in a ceramic matrix.
