Antique Radio Forums • View topic - FT-243 Crystal Grinding?

I haven't looked at the articles yet but I was told that ammonium bifluouride works to etch crystals. Easier than grinding but at some point they get a "shingles" effect and won't oscillate. The chemical is somewhat hazardous and requires careful handling. There was a 1960's article in CQ about doing this. As Carl says, thank goodness for VFO's.

Grinding and Polishing Guide | Buehler

Grinding and Polishing Guide. Grinding should commence with the finest grit size that will establish an initially flat surface and remove the effects of sectioning within a few minutes. An abrasive grit size of 180-240 [P180-P280] is coarse enough to use on specimen surfaces sectioned by an abrasive wheel. Hack-sawed, bandsawed, or other rough ...

Thermal behaviour of the tpa IONS in ZSM-5 zeolite: II ...

Thermal decomposition of Silicalite-1 crystals of various size was studied. The crystals were in as-made form and upon grinding. The DTA and DTG curves show differences in the temperature of thermal decomposition of TPA species occluded in the as-made crystals. These differences disappear upon grinding. The explanation of this phenomena is given.

Effect of crystallographic orientation on residual stress ...

Although a micro-grinding process is similar with a conventional grinding process, micro-grinding is distinctive due to size and the crystal effect. In addition to the mentioned mechanism and influence factors, the effect of material microstructure on the mechanism of micro-grinding-induced residual stress in the process needs to be considered.
