Moreover, In the TEM test, because of its test high requirement for the sample, and therefore the sample will be ground to about 1-2¦Ìm and about need to 1 hour.Then, Using a small amount of power soluble in alcohol and then repeatedly the ultrasounds. Finally, we take the upper clear liquid drops in copper screen of traits and for testing.

ÒëÎÄ£º In XRD, IR, Raman detection, glass ceramic samples were ground into powder. Moreover£¬The sample was approximately ground 1h to ensure that the size of it was  about 1-2¦Ìm in TEM test, because of its high requirement. A small amount of sample were taken into ethanol, and then ultrasound it. Finally£¬the supernatant was dropped on the idiosyncratic copper net for testing after centrifugation.
