Fabrication of high–strength alumina composite foams through gel–casting process
A water–soluble gelatin combined with polyethylene microspheres were developed to prepare alumina composite foam. Gelatin was used as the gelling agent and polyethylene was used as pore making template. On the other hand, kaolin was used to provide green strength and CuO was applied to decrease the required temperature as a sinter aid. Alumina bodies need elevate temperature for sintering, incr...
متن کاملSol-gel synthesis of ordered mesoporous alumina.
Well-ordered mesoporous alumina materials with high surface area and a narrow pore size distribution were synthesized using a sol-gel based self assembly technique.

متن کاملFabrication and Anti-Oxidation Ability of SiC-SiO2 Coated Carbon Fibers Using Sol-Gel Method
The paper proposed a method to improve the anti-oxidation performance of carbon fibers (CF) at high temperature environment by coating silicon dioxide (SiO₂) and silicon carbide (SiC). The modified sol-gel method had been used to ensure the proper interface between fibers and coating. We used polydimethylsiloxane and ethyl orthosilicate to make stable emulsion to uniformly disperse SiC nanopart...
متن کاملSol-gel synthesis and characterization of alumina-15%mullite composite nanopowder
Homogeneous distribution of mullite in the matrix of alumina can be obtained through sol-gel method. In this work, nanopowder of alumina-mullite composite was synthesized with high homogeneity and high purity. So aluminum chloride hexahydrate and tetraethyl orthosilicate were used instead of alumina or mullite nanopowder. Studying the simultaneouse thermal analysis (STA) of mullite precursor re...
