Thermal conductivity of highly porous ceramic foams with different agar concentrations

This paper discussed the creation of ceramic foams with various amounts of agar added. The foams used fly ash as the raw material in order to make them more environmentally friendly. The authors hoped that this successful use of fly ash could help to recycle that vast amounts of it that are produced each year. The effect of the various agar additions on the thermal conductivity of the foams was ...

Thermal properties of green alumina porcelain

The thermal properties, as well as bulk density, and mass loss of alumina porcelain were determined as a function of firing temperature. It was found that after sintering at 1320 ºC, the thermal conductivity and thermal diffusivity increased by ~700% and ~400%, respectively....

High-temperature thermal conductivity of ceramic fibers

This article describes comprehensive testing performed to increase understanding of how the thermal conductivity of ceramic fibers is affected. Non fibrous material content, temperature, and pressure were the main parameters investigated. Three different ceramic fiber samples were used in the research. Researchers discovered that the incorporation of aluminum reduced the thermal conductivity and consequently improved the insulation performance of the sample. An increase in pressure increased the thermal conductivity of ...

Influence of Sliding Speed on the Tribological Characteristics of Si3N4-hBN Ceramic Materials

A disc of a composite ceramic material composed of silicon nitride (Si3N4) and 20% hBN was prepared and its tribological characteristics were investigated by sliding a Si3N4 pin across its surface at different sliding speeds. The friction coefficient and wear coefficient were determined for the composite using two different test modes: one in which the pin was kept stationary and the disc was rotated on top of the pin, ...

The design of a ceramic phosphor plate with functional materials for application in high power LEDs 

Lutetium aluminum garnet activated by cerium (LuAG:Ce) materials containing functional materials (SiO2 and MgO) were prepared. These materials are used in LEDs, and they require a high thermal conductivity in order to minimize thermal aging. The functional materials were added in order to increase the thermal conductivity, as well as the luminescent properties of these materials. It was found that SiO2 did not improve the luminescent properties, but MgO ...
