“…This could be one of the reasons that the mechanical properties of the samples were improved. 24 Figure 4 shows scanning electron microscopy (SEM) images of the mullite powder calcined at 1350°C for 3 hours. The mullite particles are needle-like in morphology, with an aspect ratio of ~6.…”

With coal gangue and high alumina refractory solid wastes as raw materials, needle-like mullite powder, with an average diameter of about 1 μm, was synthesized at 1300°C by using the conventional solid-state reaction method. Mullite ceramics were derived from the inexpensive needle-like powder. Phase composition was examined by using X-ray diffraction (XRD), while morphologies of the ceramics were observed by using scanning electron microscopy. The content and distribution of elements in the sintered samples were characterized with energy dispersive spectrometer and X-ray fluorescence spectroscopy. Mechanical properties of the mullite ceramics were studied by using the three-point bending method. The aspect ratio of the needle-like mullite particles was up to 6. The mullite sample sintered at 1500°C for 3 hours had a density of 2.515 g•cm −3 , which was slightly lower than the theoretical density. Maximum fracture toughness and bending strength of the mullite ceramics were 1.82 MPa•m 1/2 and 71.76 MPa, respectively. This study realizes the resource utilization of gangue and high alumina refractory solid wastes, and the prepared mullite ceramics have good application prospect.

“…They reported that the wear values obtained by applying different wear loads and wear times to the samples increase in parallel with the increase in the applied load and wear time. Huang et al [31] stated that hardness, porosity, density and bending strength of the samples had important effects on the wear properties in their study to examine the wear properties of the composites produced by adding mullite additives at 0-10 mole ratios to zirconia (3Y-TZP). Especially adhesive and abrasive wear were observed in the samples.…”

Mullite (3Al2O3.2SiO2) and 10 mol% silica added zirconia (10 mol% SiO2 - 90 mol% ZrO2) ceramic powders were synthesized by conventional ceramic processing route. The mixtures were prepared by mechanical alloying method using zirconia ball mill in acetone environment. To synthesize mullite, Al2O3 and SiO2 powders mixture was prepared with stoichiometric proportions and fired it in the air at 1600 oC for 3 h. And the silica added zirconia composites were fired at 1300 oC for 2 h. Thus, silica - zirconia and mullite composite phases were obtained and milling and sieving processes were carried out. Then, mullite-free and 10% by weight mullite reinforced silicon oxide added zirconia mixtures were prepared by powder metallurgy method. The powders were compacted by uniaxial pressing. The formed samples were sintered in a high temperature furnace in air conditions for 1 and 5 h at 1500 and 1600 oC sintering temperatures. Finally, microstructure examinations of the composites with SEM, phase analysis with XRD, hardness, three-point bending and wear tests were performed. In addition, the results of water absorption, porosity and density from physical properties and the effect of mullite additive on the mechanical and especially wear properties of this mixture were investigated.
