碳酸 钇铵复盐结晶的形成及影响因素

The yttrium oxide obtained by calcining ammonium yttrium carbonate has a particle size more than 1 μ m. Whereas amorphous yttrium carbonate was precipitated at short aging time with low content and low molar ratio .

当反应物浓度较低、摩尔比小，陈化时间较短时得到无定型碳酸钇沉淀，煅烧 沉淀可获得粒度 （D50 ）小于0.5μm的氧化 钇。

The co precipitation behavior and the effects of impurity ions on the crystallization properties of yttrium base heavy rare earth carbonate were investigated .

本文对 钇基重稀土 碳酸盐沉淀过程中杂质铁、铝离子的共沉淀行为以及对 碳酸稀土的结晶性能和结晶效果的影响进行了研究。

Crystalline hydrated yttrium carbonate and hydrated crystalline ammonium and yttrium carbonate compound are obtained by precipitation of yttrium sulphate solutions with different amount of ammonium bicarbonate under given conditions .

在一定的条件下，从硫酸钇溶液中用碳酸氢铵沉淀时，可制得水合晶状的正 碳酸 钇或水合的晶状碳酸钇铵复盐。
