Barium permanganate may be produced by disproportionation of barium manganate in a mildly acidic solution, [3] including solutions carbon dioxide or sulfuric acid: [4] 3 BaMnO 4 + 2 CO 2 → Ba(MnO 4) 2 + 2 BaCO 3 + MnO 2 3 BaMnO 4 + 2 H 2 SO 4 → Ba(MnO 4) 2 + 2 BaSO 4 + MnO 2 + 2 H 2 O. It can also be prepared by oxidation of barium ...

The manganate(VI) ion is a d 1 ion and is tetrahedral with bond angles of approximately 109.5°. The Mn−O bond lengths in BaMnO 4 and K 2 MnO 4 are identical at 1.66 Å. In comparison, the Mn-O bond length in MnO 2− 4 is longer than in MnO 4 − of 1.56 Å and shorter than the Mn−O bond found in MnO 2, 1.89 Å.
A permanganate (/ p ər ˈ m æ ŋ ɡ ə n eɪ t, p ɜːr-/) [1] is a chemical compound with the manganate(VII) ion, MnO − 4 , the conjugate base of permanganic acid . Because the manganese atom has a +7 oxidation state , the permanganate(VII) ion is a strong oxidising agent .

Beryllium is a component of several dental alloys. [129] [130] Beryllium is used in X-ray windows because it is transparent to X-rays, allowing for clearer and more efficient imaging. [131] In medical imaging equipment, such as CT scanners and mammography machines, beryllium's strength and light weight enhance durability and performance. [132]
Beryl (/ ˈ b ɛr əl / BERR-əl) is a mineral composed of beryllium aluminium silicate with the chemical formula Be 3 Al 2 Si 6 O 18. [6] Well-known varieties of beryl include emerald and aquamarine. Naturally occurring hexagonal crystals of beryl can be up to several meters in size, but terminated crystals are relatively rare. Pure beryl is ...
