The Pourbaix diagram for chromium in pure water, perchloric acid, or sodium hydroxide [1] [2] Chromium compounds are compounds containing the element chromium (Cr). Chromium is a member of group 6 of the transition metals. The +3 and +6 states occur most commonly within chromium compounds, followed by +2; charges of +1, +4 and +5 for chromium ...
A borate is any of a range of boron oxyanions, anions containing boron and oxygen, such as orthoborate BO 3− 3, metaborate BO − 2, or tetraborate B 4 O 2− 7; or any salt of such anions, such as sodium metaborate, Na + [BO 2] − and borax (Na +) 2 [B 4 O 7] 2−.

Chromium is a chemical element; it has symbol Cr and atomic number 24. It is the first element in group 6. It is a steely-grey, lustrous, hard, and brittle transition metal. [10] Chromium is valued for its high corrosion resistance and hardness.
Chromium(III) boride, also known as chromium monoboride (CrB), is an inorganic compound with the chemical formula CrB. [2] It is one of the six stable binary borides of chromium, which also include Cr 2 B, Cr 5 B 3 , Cr 3 B 4 , CrB 2 , and CrB 4 . [ 3 ]
Organoboron chemistry is mainly of commercial value in the pharmaceutical industry. Triethylborane was used to ignite the JP-7 fuel of the Pratt & Whitney J58 variable cycle engines powering the Lockheed SR-71 Blackbird. Organoboron compounds have long been discussed for use as boron delivery agents in neutron capture therapy of cancer. [49]

A metaborate is a borate anion consisting of boron and oxygen, with empirical formula BO − 2. Metaborate also refers to any salt or ester of such anion (e.g. salts such as sodium metaborate NaBO 2 or calcium metaborate Ca(BO 2) 2, and esters such as methyl metaborate CH 3 BO 2). Metaborate is one of the boron's oxyanions.
