Effect of transition-metal-ion doping on high temperature thermal expansion of 3:2 mullite—An in situ, high temperature, synchrotron diffraction study

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

“…The QLF is a radiation heating furnace that can be used to conduct HTXRD investigations of ceramics in air up to 2000 • C in air. [32][33][34][35] The details of the construction, operation and capabilities of the CIP detector, used in these studies, are reported elsewhere. 36 The CIP detector allows for simultaneous acquisition of diffracted X-ray intensities over a 2θ range extending from 2 • to 35 • , thus eliminating any time dependence in XRD pattern acquisition.…”

“…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.…”

Effects of pyrolusite additive on the microstructure and mechanical strength of corundum–mullite ceramics

“…Corundum-mullite material, as one widely used in duplex ceramics for application [1,2], centralizes the advantages of corundum and mullite ceramics and is regarded as a quite promising engineering material at high temperatures because of its remarkable thermal shock resistance, high temperature resistance and creep characteristics [3][4][5]. Moreover, the duplex ceramic has been widely applied in kiln furniture at high temperature, such as refractory bricks and pushers [6,7].…”

Effect of mechanical activation and microwave heating on synthesis and sintering of nano-structured mullite

“…Mullite is a promising ceramic with the high temperature applications due to its low thermal expansion, high creep resistance and good thermal shock behaviour and also with good chemical, mechanical and electrical properties [1][2][3][4][5]. Many works have reported the use of kaolin as a key material for synthesis of mullite ceramics [6][7][8].…”
