Formation of Porous Fumed Silica Coating on the Surface of Glass Fibers by a Dry Mechanical Processing Technique

Smart Powder Processing for Advanced Materials

“…The second example is to make high efficient thermal insulation materials [25][26][27] . Interest in thermal insulation materials has been intensified globally, because escalating energy costs signified the importance of efficient thermal insulation.…”

“…1 showed the examples of unique microstructures created by the par ticle bonding technique, which led to various kinds of applications such as multi-layered composite particles for the drug delivery systems (DDS) 6) , self-assemble structures for electronic devices, composite porous materials for fuel cell electrodes, and nano-porous materials. In this paper, first, its application examples for advanced material production would be explained, including the development of fuel cell electrodes [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] and high efficient thermal insulation materials [25][26][27] . Fur thermore, by making use of these features, a new one-pot processing method to synthesize nanoparticles without applying extra heat was developed.…”

Preparation of fumed silica compacts for thermal insulation using wet processing method

“…The fumed silica is a kind of promising thermal insulating material for its low thermal conductivity, which is attributed to its high porosity and nanoscale porous structure. Recently, a few researches have concentrated on the preparation of fumed silica compacts for thermal insulation . In order to improve its mechanical reliability, the glass fibers were introduced.…”

Effects of Powder Additives on Thermal Shrinkage of Nanoporous Silica Insulation

“…Fumed silica, a high-purity non-crystalline silica, is produced by fusing naturally occurring quartz crystals of high purity at approximately 2000°C. It has many excellent properties, and especially its thermal insulating property is superior to other types of thermal insulations due to the nano-scale particle size (about 20 nm) [3][4][5]. Low thermal conductivity makes it a useful and basic material for thermal insulation [6].…”
