The quartz plate
dissolution was carried out in 10 ml of 40 % hydrofluoric acid at room temperature and pressure.
Ferrocene (powder), 1,2dichlorobenzene, and Quartz plate
(2-inch) were purchased from Alfa-Aesar England.
It is a stamped foil element heater with a quartz plate
in front of the elements.
Wireless-electrodeless QCM (WE-QCM) system were recently developed, where a naked ATcut quartz plate
was driven by the line antenna or the flat antenna contactlessly, (11) and achieved high frequency QCMs with fundamental resonance frequencies up to 180 MHz.

There is rough, black quartz, full of inclusions, that decrepitates violently on heating; there is Japan-law twinned quartz; there are doubly terminated quartz crystals that have smoky clouds in each tip; there are quartz crystals that have developed to show only three rhombohedral faces on each termination; there are crystals whose tips have etched back to reveal phantoms within; there are odd crystals tha t have grown in multiple parallel orientation in what Looks like wild exuberance, and there are fragile spheroids of radiating, wafer-thin quartz plates
locked in matrix.
If quartz plates
are utilized in the UV curing process, they should be cleaned regularly to ensure the UV transmission properties are still effective.
