Zinc bromide is a white ionic solid.

Uses

* Organic chemistry as a lewis acid.
* As a transparent shield against radiation.ref|doe ref|hps Two glass panes filled with a strong aqueous solution of zinc bromide has a very high density, which can then be used as a window on a hot cell. This type of window has the advantage over lead glass in that it will not darken as a result of exposure to radiation. All glass will darken slowly over time due to radiation, however this is especially true in a hot cell, where exceptional levels of radiation are present. The advantage of an aqueous salt solution is that any radiation damage will be last less than a millisecond, so the shield will undergo self-repair.
* The Zinc bromide battery.
