A series of new low calcium CO 2 sequestration cementitious materials (LCC) with different Ca/Si ratios were prepared by sintering waste concrete fine powder (WCP) and calcium carbide slag (CCS) at different ratios. Their carbonation reaction activity, carbonation hardening properties, phase assemblages, and microstructure were …

Mechanism: atomization method generally uses high-pressure gas, high-pressure liquid or high-speed rotating blades to break the molten metal or alloy at high temperature and high pressure into fine droplets, and then condense in the collector to obtain ultra-fine metal powder. There is no chemical change in this process.

A satisfactory fine grinding sequence might involve SiC papers with grit sizes of 240, 320, 400, and 600 grit [P280, P400, P800 and P1200]. ... One option is to planar grind the specimens with a conventional alumina or Silicon carbide grinding stone. This requires a special purpose machine, as the stone must rotate at a high speed, ≥1500 rpm ...

The total degree of reduction achieves 98–99%; the precipitation takes place on seed particles 10–50 μm in size, which are produced by fine powder milling. The precipitation degree on the powder achieves 96–97%. Particle sizes of the powder produced range from 200 to 500 μm; particles are spherical and grain texture is dense.

Atomised Ferrosilicon. Atomised ferrosilicon is a powder consisting of 15% Si whereby liquid melt is atomized by air or steam. It is used for applications in dense media separation technology. This is a process where a suspension of dense powder in water is used to form a type of heavier liquid to separate mineral particles in a sink-float process.

Remove the boiled shells from the water and spread them out evenly on a baking sheet. Toast your eggshells in the oven at 225 F for at least 25 minutes, until the eggshells are completely bone-dry. This will make your eggshells easier to process and the powder less clumpy. Let the eggshells cool for around 30 minutes.

Metallographic grinding and polishing processes differ depending on the sample material. These differences usually affect the consumables required or the number of necessary grinding and polishing steps. For example, steel with a hardness between 35 and 65 HRC (medium-hard to hard steels) is relatively easy to prepare.
