Bismuth dissolves in concentrated sulfuric acid to make bismuth(III) sulfate and sulfur dioxide. [34] 6 H 2 SO 4 + 2 Bi → 6 H 2 O + Bi 2 (SO 4) 3 + 3 SO 2. It reacts with nitric acid to make bismuth(III) nitrate (which decomposes into nitrogen dioxide when heated [39]). [40] Bi + 6 HNO 3 → 3 H 2 O + 3 NO 2 + Bi(NO 3) 3

Bismuth titanate ceramics can be produced by heating a mixture of bismuth and titanium oxides. Bi 12 TiO 20 forms at 730–850 °C, and melts when the temperature is raised above 875 °C, decomposing in the melt to Bi 4 Ti 3 O 12 and Bi 2 O 3. [4]
Bismuth silicon oxide is a solid inorganic compound of bismuth, silicon and oxygen. Its most common chemical formula is Bi 12 SiO 20 , though other compositions are also known. It occurs naturally as the mineral sillénite and can be produced synthetically, by heating a mixture of bismuth and silicon oxides.
Bismuth hydrate is a component used in milk of bismuth [3] which is used in gastrointestinal disorders as a protective agent. [4] Aqueous ammonia reacts with bismuth(III) ions to precipitate white bismuth hydroxide. [5] It is used as an absorbent, and in the hydrolysis of ribonucleic acid.
