  • Preparation of pressureless-sintered dense cordierite ceramics with . . .
    This study synthesized mesoporous cordierite precursor powders using a non-hydrolytic sol-gel method facilitated by structure-directing agents Dense cordierite ceramics were subsequently prepared via pressureless sintering of these mesoporous powders Furthermore, the effects of the preparation process on the microstructure, density, and mechanical properties of the sintered cordierite
  • Exceptionally optimized millimeter-wave properties of cordierite-based . . .
    Fig 8 highlights the exceptional superiority of our results in comparison to cordierite-based materials Our study showcases a highly optimized set of properties that are commercially attractive for millimeter-wave applications
  • Cordierite - an overview | ScienceDirect Topics
    Cordierite Cordierite is a ring silicate, typically with low refractive indices and birefringence, and in thin section tends to be confused with quartz or feldspars Twinning is known on {110} and {310}, forming simple, lamellar, or cyclic twins It has the composition (Mg,Fe)2 [Si 5 Al 4 O 18] nH 2 O, and is mainly found in metamorphic rocks The Fe Mg ratios in coexisting cordierite and
  • Mechanism of cordierite formation obtained by high temperature . . .
    Cordierite (2MgO·2Al2 O 3 ·5SiO 2) is a kind of important ceramic with low thermal expansion coefficient and low dielectric constant In this study, the influence of raw material compositions and various sintering temperatures on the synthesis mechanism and reaction path of cordierite were studied The results reveal that the binary compounds forsterite and magnesia-alumina spinel are
  • High-strength porous cordierite ceramics from emulsions stabilized by . . .
    In this work, we developed a method for preparing high-strength porous cordierite ceramics by using emulsions stabilized by plate-like cordierite particles Emulsification was achieved by mechanically shearing an oil-water mixture composed of octane and cordierite suspension containing pentylamine
  • Low-temperature cordierite ceramics with porous structure for thermal . . .
    This article shows the results of the study of low-temperature (1100−1150 °C) porous ceramics of cordierite composition The technological manufacturi…
  • Dense and high flexural strength cordierite ceramics doped with Li
    High-strength cordierite ceramics with Li 2 O were fabricated by non-pressure sintering The results showed that the addition of Li 2O significantly reduced the sintering temperature and expanded the sintering range Additionally, the mechanical strength of the samples clearly increased after Li2 O doping In particular, the sample with 0 5 wt% Li 2O sintered at 1250 °C showed the best
  • Origin of the coeval cordierite granite, metapelite and diorite in the . . .
    The origin of coeval magmatic and metamorphic rock associations is of great significance in tectonic interpretations In this study, spatially associa…
  • Additive manufacturing of cordierite materials by digital light . . .
    Cordierite ceramic material is exceptionally resistant to chemical corrosion, low thermal expansion, and thermal shock, which would be a suitable candidate for thermal applications Cordierite materials ( (Mg, Fe)₂Al₄Si₅O₁₈) were additive manufactured by digital light processing (DLP)
  • Anomalous thermal expansion of cordierite, Mg2Al4Si5O18, understood . . .
    Cordierite, Mg2Al4Si5O18, finds widespread use as a high-performance material because of its very low thermal expansion, but its thermal properties ar…
