High-entropy oxides (HEOs), which contain five or more metal cations that are generally
thought to be randomly mixed in a crystalline oxide lattice, can exhibit unique and enhanced …

In this review, the main technological processes involved in the production of color in
glasses, ceramics and pigments are reported. Iron (as oxides or dispersed ion) is the main …

Dry reforming of methane (DRM) is a promising method to utilize two greenhouse gases,
such as CH4 and CO2, to produce synthesis gas. In the current work, both monometallic Ni …

Iron catalysts have been extensively investigated for the direct hydrogenation of CO 2 into
light olefins and long-chain hydrocarbons. However, rapid catalyst deactivation is caused by …

The new zero-chrome multicomponent (Mg, Zn)[Al, Fe] 2 O 4 spinels were synthesized in
this study, which are potential candidates for refractory matrix and aggregate to substitute …

Year by year, the total demand for cement production has been growing. To be more
competitive, cement producers have implemented new operating practices based on new …

Industrial magnesia-spinel bricks destined for thermal shock applications often show more
flexibility and improved crack growth resistance. Components from the spinel structure group …

The drawback of the hydrothermal technique is driven by the fact that it is a time-consuming
operation, which greatly impedes its commercial application. To overcome this issue …

This paper describes a novel process, hematite involved roasting− alkaline leaching− Bayer
digestion, to extract silica and alumina from high-alumina coal gangue (HACG). The phase …

Coking is still a major cause of catalyst deactivation in catalytic methane reforming
processes. In this work, doping the support of Ni/γ-Al 2 O 3 catalysts with iron to provide …
