由于氧化锆和氧化钇同属难挥发化合物,且锆有非常复杂的发射光谱和高背景,这就使得用发射光谱测定其中少量氧化钇相当困难,但用 X 荧光测定却相当容易。对少量样品,采用双层粉末压片增量法是一种简单可靠的方法。1.增量样片的制备将50毫克氧化钇与450毫克硼酸混合,充分磨匀。在4个玛瑙乳钵中各称取氧化锆样品100毫克,分别加入上述氧化钇-硼酸混合物0、20、30、40毫克(相当于加氧化钇
Since zirconium oxide and yttrium oxide are both refractory compounds, and zirconium has a very complicated emission spectrum and a high background, this makes it quite difficult to measure a small amount of yttrium oxide by emission spectroscopy, but it is quite easy to measure with X-fluorescence. For a small number of samples, the double powder tablet increment method is a simple and reliable method. 1. Preparation of Incremental Samples 50 mg of yttrium oxide and 450 mg of boric acid were mixed thoroughly and thoroughly. In 4 agate mortar each weighed 100 mg of zirconia samples were added to the above yttria - boric acid mixture 0,20,30,40 mg (equivalent to plus yttrium oxide
