Mullite fibers prepared from an inorganic sol–gel precursor

Production of submicrometric fibers of mullite by solution blow spinning (SBS)

“…The presence of intermediary spinel phase (JCPDS 37-1483) is observed after firing at 1000 1C. The reflections due to the mullite phase were identical with those reported in other studies [9,[17][18][19]. The samples fired at 1000 1C presented an average crystallite size of 18 nm, which is consistent with the presence of only one mullite reflection between 25.91 and 26.21.…”

“…The PVCþ TEOSþAN fibers presented an interconnected morphology, with some beads and beaded fibers. This morphology is not observed in mullite fibers produced in electrospinning process [4,8,9] or using sol-gel technology [5,7], and can be particularly interesting in applications such as reinforcements to composites, and in several others that require substrates with high specific surface area as in catalysis and filtration membranes.…”

“…The production of mullite fibers, mostly nanometric and submicrometric fibers, has attracted considerable interest of many technological sectors, because of the excellent properties they exhibit and the large number of applications, ranging from reinforcements for metals, ceramics, and polymers, high temperature structural materials, high temperature plasticizing structural ceramics and insulating systems to membrane technology [4][5][6][7][8][9].…”

Preparation and Grain-Growth of Magnesia-Alumina Spinel/Yttrium Aluminum Garnet Composite Fibers

“…Two main processes for the manufacturing of ceramic fibers existed, including melt-spinning processes and sol-gel spinning processes [11]. Many successful processes have been reported in the preparation of YAG fibers by the sol-gel method [12,13].…”

High‐Temperature Shear Strength and Bonding Mechanism of the Mullite Ceramic/Fiber Brick Component Joined by Phosphate Adhesive

“…Because of the elastic property of the fiber brick, the joined system can be endued proper elastic property, which greatly overcomes the brittleness of the ceramics. On the other hand, this joined system broadens the applications of the ceramic materials, such as, insulation materials in the furnace and sealing systems in the aerospace field . A critical issue for a wide use of ceramic/fiber system is the development of the joining methods.…”
