GRINDING Surface layers damaged by cutting must be removed by grinding. Mounted specimens are ground with rotating discs of abrasive paper, for example wet silicon carbide paper. The coarseness of the paper is indicated by a number: the number of grains of silicon carbide per square inch. So, for example, 180 grit paper is coarser than 1200 grit.

The 0D Cs 3 BiCl 6 and 1D Cs 3 Bi 2 Cl 9 metal halides can be synthesized by adjusting the Cs/Bi feed ratio at room temperature, and they exhibit bright orange broadband emission after Mn 2+ doping. The reversible structural switch of Mn-doped Cs 3 BiCl 6 and Cs 3 Bi 2 Cl 9 metal halides could be flexibly adjusted through post addition of the CsCl/BiCl 3 precursors.
