LanthanumfluorideanhydrousREOwhitepowder - Preparation Method
Open Data Verified Data
lanthanum oxide was dissolved in hydrochloric acid and diluted to 100-48% g/L (based on La2 03), and the solution was heated to 70-80 °c and precipitated with hydrofluoric acid. The precipitate was washed, filtered, dried, pulverized and vacuum dehydrated to give lanthanum fluoride.
