The Rheology of Graphene Oxide Dispersions in Highly Viscous Epoxy Resin: The Anomalies in Properties as Advantages for Developing Film Binders

Liquids
Graphene oxide (GO) has been successfully used as a filler to modify various properties of polymers and fiber-reinforced composites. The resulting properties depend on the filler content and on the distribution of GO in the polymer matrix.

Oxidation Behavior of MgO‐C Refractories Containing Metallic Aluminum, Calcium Magnesium Aluminate Aggregates, and Carbores P

steel research international, Volume 96, Issue 5, May 2025.
The study investigates the oxidation resistance of MgO‐C refractories enhanced with calcium magnesium aluminate (CMA) aggregates, metallic aluminum, and Carbores P from 800 to 1600 °C. CMA retains resistance up to 1200 °C but decreases above. Carbores P protects up to 1000 °C, while metallic aluminum shows the highest resistance across the range.

Impact of the Replacement of Pitch Binder by the Environmentally Friendly Binder System Based on Lactose and Tannin on the Properties of Carbon‐Bonded Alumina Filters

steel research international, Volume 96, Issue 5, May 2025.
To improve the environmental sustainability of carbon‐bonded alumina filters, the replacement of coal tar pitch by an environment‐friendly binder system based on lactose and tannin is investigated. According to the results of the (thermo)mechanical filter properties, total carbon content, and microstructure, filter structures based on lactose/tannin ...

Geometric and Constitutive Modeling of MgO–C Refractories Based on Recyclates for Thermomechanical Simulations

Proceedings in Applied Mathematics and Mechanics, Volume 25, Issue 1, March 2025.
ABSTRACT Refractories are polycrystalline, porous, heterogeneous, and nonmetallic materials utilized as protective liners in high‐temperature manufacturing processes. Microscopic and mechanical characterization studies of MgO–C refractories in the literature show a strong correlation between the underlying microstructure and the thermomechanical ...
