Yttrium carbonate can react with most acids to form corresponding salts. It decomposes into Y2O3 when heated at 900 ℃. The yttrium extract is neutralized with ammonia water, added with ammonium bicarbonate to precipitate yttrium carbonate. After filtration, washing, centrifugation and drying, the precipitate is yttrium carbonate.
【Application】
1.It is suitable for ceramics manufacturing.
2.It is resistant to many reactive molten metals such as titanium or uranium.
3.For producing of multilayer ceramic capacitors, Lanthanum fluoride is also employed as a dopant to reduce the Curie temperature of the barium titanate substrate due to its special properties.
