Synthesis of mixed-metal carbonates by grinding

Feb 01, 1989· The grinding synthesis route is not limited to mixed carbonates with the calcite structure. When strontium and barium chloride are ground together with sodium carbonate for 15 h, a phase with the aragonite structure is formed with a unit cell intermediate between the two end member carbonates. Beyond providing fresh surface area, grinding

Mechanical Grinding an overview ScienceDirect Topics

Low-temperature grinding produces compressive residual stresses and improves fatigue life. This beneficial result is due to the mechanical grinding force applied to the surface which has a similar effect to surface peening. Conversely, high-temperature grinding of hardened components produces tensile residual stresses that shorten fatigue life.
