Suoyi Spherical Yttrium Oxyfluoride Yof kanggo Thermal Spray Coating Plasma Powder

Yttrium oxyfluoride sing diwakili dening YOF biasane duwe struktur kristal rhombohedral ing suhu kamar, struktur kristal kubik utawa tetragonal ing suhu sing luwih dhuwur tinimbang 600 ° C, lan 550 nganti 600 ° C nalika didinginake saka suhu dhuwur. Dikenal nuduhake transisi fase saka kubik utawa tetragonal menyang rhombohedral. Wiwit transisi fase iki diiringi owah-owahan volume, stres sing ana gandhengane karo transisi fase digawe nalika pendinginan ing yttrium oxyfluoride. Nalika yttrium oxyfluoride dipanasake saka suhu kamar nganti suhu sing luwih dhuwur tinimbang 600 ° C, stres amarga transisi fase sing padha diasilake. Contone, yen yttrium oxyfluoride duwe wangun sing kena pengaruh banget amarga distorsi amarga owah-owahan volume, kayata film utawa akeh, stres iki nyebabake retak lan retak.
