Rare-earth phosphates (REPO<sub>4</sub>) are regarded as one of the promising thermal/environmental barrier coating (T/EBC) materials for SiC<sub>f</sub>/SiC ceramic matrix composites (SiC-CMCs) owing to their excellent resistance water vapor and CaO–MgO–Al<sub>2</sub>O<sub>3</sub>–SiO<sub>2</sub> (CMAS). Nevertheless, a relatively high thermal conductivity (<i>κ</i>) REPO<sub>4</sub> becomes bottleneck practical applications. In this work, novel xenotime-type high-entropy...
Abstract The Si‐O‐C ceramics were prepared by polymer‐derived ceramic method using polysiloxane/FeCl 3 as precursor with the FeCl content of 1.0 wt%. microstructure, dielectric properties, and electromagnetic wave (EMW) absorbing properties in X band investigated. It was found that pyrolysis temperature has a great influence on amount in‐situ formed CNTs transformation from to 1D SiC nanostructures. With rising 1000 1500°C, various morphologies including microspheres, needle‐like SiC,...

Abstract The paper investigated the effects of different amounts (0%, 3%, 6%, 9%) in situ multilayer graphene/MgAl 2 O 4 composite powders on slag resistance, thermal shock and oxidation resistance low‐carbon MgO‐C refractories. Comparing with commercial MgAl , has higher lattice strain crystal, which can trap more Mn Fe ions, resulting better resistance. decarbonation layer specimen 3% is 9.71 mm, lower than not only other contents but also containing carbon black/MgAl powders. Moreover,...
Abstract Previous studies have indicated that hydratable magnesium carboxylate (HMC) exhibits potential as an MgO‐based binder, but its limited medium‐temperature strength has hindered widespread industrial application. In this study, the incorporation of MgO fumes into castables is intended to react with microsilica form magnesium–silicate–hydrate (M–S–H), and synergistic effect HMC M–S–H anticipated improve mechanical properties at intermediate temperatures. The effects on HMC‐bonded were...

The XRD, Raman, scanning electron microscope energy‐dispersive spectroscopy, VNA network analysis carried out effects addition azodicarbonamide (AC) foaming agent on phase compositions, microstructure, products. results indicated that an AC contributed to formation distinct...
Abstract Mullite castables, employed as the lining materials in high‐salinity organic waste liquids incinerators, are subjected to severe alkali attack. The corrosion resistance of four types mullite castables based on Mullite60 (M60), Mullite45 (M45), Fire clay (FC), and Glass‐rich (GRM) materials, named CM60, CM45, CFC, CGRM respectively, was investigated using a static crucible testing method with Na 2 CO 3 SO 4 under 1100°C this study. results showed that demonstrated exceptional .
