标题:Mechanochemical Changes Of Weinschenkite-Type Rpo4.2H2O (R = Dy,Y,Er,Or Yb) By Grinding And Thermal Reactions Of The Ground Specimens
摘要:It Is Reported That,On Mechanochemical Treatment,Weinschenkite‐type Rpo4.2H2O (R = Dy,Y,Or Er) Gradually Transforms Into Rhabdophane‐type Rpo4. Nh2O (N = 0.5 To 1) And Weinschenkite‐type Ybpo4.2H2O Into Xenotime‐type Ybpo4,At Room Temperature In Air. Rhabdophane‐type Ypo4.0.8H2O And Erpo4.0.9H2O Obtained By Grinding Weinschenkite‐type Rpo4.2H2O (R=y Or Er) Are New. The New Rhabdophane‐type Ypo4.0.8H2O And Erpo4.0.9H2O Gradually Transform To Xenotime‐type Ypo4 And Erpo4 When Heated Above 900oc (R = Y) And 700oc (R = Er) In Air.

摘要:Methods for producing substantially single phase yttrium phosphate which exhibits the xenotime crystal structure are disclosed. The methods can be practiced without the use of high temperatures (e.g., the methods can be practiced at temperatures less than 1000° C.). The resulting yttrium phosphate can be in the form of particles which comprise interwoven strands of crystals of yttrium phosphate and/or nanoparticles prepared from such particles.
