Structure and oxidation resistance of micro-cellular Si–SiC foams derived from natural resins

Si-SiC composite foams were prepared using tannin-based foams as templates. The foams were prepared by four different methods for the determination of which method would best produce a foam with a pore size under 200 µm. The foam samples were characterized by SEM, XRD, and Raman ...

Synthesis and characterization of silica aerogel and its composite materials

Composite silica aerogels were prepared using sodium silicate and ceramics fibers. The thermal conductivities of these composites were investigated to determine how effective they would be as thermal insulation. As temperature increased to 400oC, the thermal conductivity of these composites only increased from 0.0266 to 0.0572 W/(...

Preparation of Porous Mullite Ceramics Using Fly Ash Cenosphere as a Pore‐Forming Agent by Gelcasting Process

This article discusses the creation of a porous mullite ceramic through the incorporation of fly ash cenospheres (FAC) into mullite powder through the gelcasting process. Sintering temperature and the amount of FAC added were investigated as factors affecting density and strength. The authors found that ...

Thermal conductivity of porous materials

The effects of solid phase thermal conductivity, pore thermal conductivity, and pore volume fraction on the measured effective thermal conductivity of porous ceramics with pore volume fractions of 4 to 95% were investigated. The experimental results were then compared with pre-existing numerical models. It was found that ...

Design of ceramic phosphor plate with functional materials for applications in high power LEDs 

Traditionally, white LED's are made by mixing phosphor with an epoxy resin. But, the phosphor is not always evenly distributed, and the epoxy resin has a low thermal conductivity resulting in accelerated thermal aging during operation. This article studies the effects of implementing a ceramic ...
