  Iron oxides as efficient sorbents for CO2 capture

  201951 · It was shown that iron oxides have active sites exposed at the surface which can react with the gaseous molecules of CO 2 [24]. Materials treated in grinding processes decrease in the particle size, forming a new fresh surfaces and creating more active sites which translates to increase of the surface area [25], [26].

  Direct Reduction of Ferrous Oxides to form an Iron-Rich …

  2015121 · In this study, production of sponge iron by direct reduction of oxides and the effect of reductant on metallization were investigated. In the first stage of the study, scale formed during hot rolling of slabs was reduced in a rotating furnace using solid and gas reductants. Coal was used as solid reductant and hydrogen released from the …

  The Best Sandpaper for Metal - Choosing the Right Grain

  Aluminum oxide is commonly used in metalworking. As a material, it is durable, hard, and can be used to grind, sand, and polish a wide range of materials, including steel, cast iron, and aluminum. Sandpaper intended for metalworking tends to be closed-coated, meaning that abrasive particles cover nearly the entire surface of the backing material.

  The Selection Of Abrasive Materials For Abrasive Tools

  20191220 · Attention must also be paid to the chemical affinity between abrasives and workpiece materials, especially the affinity between some difficult-to-machine materials and abrasives is obvious. For example, when silicon carbide abrasives are used to grind heat-resistant alloys, because silicon carbide can self-chemically react with iron and under the …

  Microscopic characterization and modeling of oxide layer for ...

  201938 · Electrolytic in-process dressing (ELID) is a grinding technique used to generate high-quality surfaces on hard and brittle material. Oxide layer formed on grinding wheel during ELID grinding heavily influences the surface roughness of the workpiece. To study the microscopic structure of the oxide layer and model the thickness of it, we …
