Influence of Slag Composition on the Distribution Behavior of Cu between Liquid Sulfide and Cu-Containing Multicomponent Slag via Thermodynamic and Kinetic Assessment

Metals, 2021
At present, copper smelting slag is not effectively recycled and is wasted. Copper smelting slag contains FexO at more than 40 mass%. For the utilization of copper slag as a Fe resource, it is necessary to separate the Cu in the slag.

Solubility of Chlorine in Aluminosilicate Slag Systems.

ISIJ International, 2000
Thermodynamic properties of chlorine in the CaO–SiO2–Al2O3, Na2O–SiO2–Al2O3and CaO–SiO2–Al2O3–Na2O slags have been investigated in the present study. The experiments were carried out using gas-slag equilibrium, controlling both PO2 and PCl2simultaneously (PO2=10-16 - 10-19atm, PCl2 = 10-10 - 10-13 atm at 1673–1748 K), and the solubility of chlorine in ...

Unlocking Strength‐Toughness Dilemma in High‐Entropy Borides by Intragranular Microstructural Reconstruction

Advanced Science, EarlyView.
An extreme non‐equilibrium process combining heavy direct current sintering and TiSi2 addition is used to construct intragranular energy dissipation units within high‐entropy boride ceramics to overcome the strength‐toughness trade‐off. The resulting ceramic demonstrates attractive mechanical properties with a flexural strength of 887 MPa and a ...

Distinct Neuropsychiatric Profiles Associated With 17p11.2 Deletions and RAI1 Variants in Smith–Magenis Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Smith–Magenis syndrome (SMS) results from either a recurrent 17p11.2 deletion or pathogenic variants in the retinoic acid induced 1 gene (RAI1). While neurodevelopmental impairment and behavioral dysregulation are well recognized, systematic genotype‐stratified analyses across psychiatric domains remain limited.

Exploring Influence of MgO/Na2O on Melting Characteristics and Viscosity–Temperature Characteristics of Coal Slags Under Entrained Flow Gasification Condition

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Characteristics of high alkali in Zhundong coal ash may cause ash‐related slag discharge problems at entrained‐flow‐bed (EFB) gasifier. In this study, through exploring melting characteristics and viscosity–temperature characteristics, it is found that MN05, MN14, and MN23 show low FTs (< 1160°C).

Inverse Vulcanized Sulfur Polymer Composites From Poultry‐Industry Products and Lignocellulosic Biomass Waste

Journal of Applied Polymer Science, EarlyView.
This work explores the use of various fillers, including eggshell powder, feather meal, peanut hulls, and sawdust to reinforce a base binder GFS90 (comprised of 90 wt.% sulfur, 5 wt.% chicken fat, and 5 wt.% sunflower oil). The resulting composites showed impressive compressive strengths ranging from 15.3 to 36.2 MPa, making them a potential ...
