Growth of textured mullite fibers using a quadrupole lamp furnace

In situ studies of oxidation of ZrB2 and ZrB2–SiC composites at high temperatures

“…The effect of SiC on the oxidation of ZrB 2 in ZrB 2 -SiC composites was also evaluated. A specially designed quadrupole lamp furnace (QLF), which allows heating of samples up to 2000 • C in air, [32][33][34][35] was used in conjunction with a high resolution curved image plate (CIP) detector for these studies. 36,37 Using this method, the oxidation of ZrB 2 to ZrO 2 was monitored in real time, independent of other accompanying processes.…”

Tailoring the microstructure of mechanoactivated Al2O3 and SiO2 mixtures with TiO2 addition

“…An alternative way to produce interlocking microstructured mullite ceramics is via in situ processing technique. For a conventional solid-state reaction process, in situ anisotropic grain growth usually takes place at very high temperatures (>1600 • C) [5][6][7][8]. This is because mullite ceramics prepared in this way experienced densification before mullite phase formation.…”

“…This suppressed anisotropic growth of mullite grains. In this case, ultra high temperature is essential for the formation of a eutectic liquid to maintain the anisotropic grain growth of mullite in a fully densified sample [5][6][7][8].…”

Mullite fibres prepared by sol–gel method using polyvinyl butyral

“…In order to overcome the difficulties, the sol-gel technique is employed to synthesize the high-melting point ceramic fibres. [9][10][11][12][13] The sol is hydrolyzed and then condensed or polymerized/co-polymerized until an appropriate viscosity for spinning is achieved for production of fibres. In comparison to high temperature melt technique, the sol-gel method not only makes the starting materials homogeneous, but * Corresponding author.…”
