Whilst mercury has been utilized for many functions all through history, its use is currently progressively restricted due to its harmful features.
Yet another kind is Technical Grade Mercury. Complex grade mercury is considerably less pure in comparison to the ninety nine.99% range but remains to be suited to a wide array of industrial programs. It is commonly Employed in the creation of electrical switches and relays. The liquid character of mercury will allow it for making and split electrical contacts easily, that is essential for the appropriate operating of those units.
