Thulium(III) sulfate is an inorganic compound of thulium, with the molecular formula Tm2(SO4)3.

Contents

It has received little scientific attention as its solubility in water was only determined in 2023 [1] despite it being known since at least 1911. [3] [4]

Preparation

Thulium(III) oxide has been reported to react with strong acids with hydrochloric acid being explicitly mentioned. [5] Sulfuric acid is also a strong acid that forms sulfate salts. [6]

Tm2O3 + 3 H2SO4 → Tm2(SO4)3 + 3 H2O

Properties

Thulium sulfate can form an octahydrate. [7] [8]

It can also be used as a dopant for e.g. lithium borate glass that contains copper nanoparticles in order to limit photo-darkening [9] or in thermoluminescent dosimeters. [10]

It undergoes ion exchange with barium bromate to yield thulium(III) bromate and barium sulfate which precipitates from the aqueous solution. [3]

Tm2(SO4)3 + 3 Ba(BrO3)2 → 2 Tm(BrO3)3 + 3 BaSO4↓
