- An yttrium compound is a chemical compound containing yttrium (element symbol: Y). Among these compounds, yttrium generally has a +3 valence. The solubility properties of yttrium compounds are similar to those of the lanthanides. For example oxalates and carbonates are hardly soluble in water, but soluble in excess oxalate or carbonate solutions as complexes are formed. Sulfates and double sulfates are generally soluble. They resemble the "yttrium group" of heavy lanthanide elements. (en)
- 钇化合物是钇（元素符号：Y）形成的化合物，在这些化合物中，钇一般显+3价。钇化合物的溶解度性质与镧系元素铕至镥的化合物有一定相似之处，如碳酸盐和草酸盐难溶于水，而可溶于过量的碳酸盐或草酸盐溶液，以及硫酸盐复盐可溶于水，这些化合物被归为“钇组”。 (zh)
