Lithium niobate decomposition

Lithium niobate decomposition, 264 formation mechanism, 35-37 Lithium tantalate decomposition, 263 formation mechanism, 35-37 LO-TO splitting, 242... 

Another method of raw material decomposition is based on the fluorination of the raw material by the hydrofluoride method. No published data exists on hydrofluoride decomposition of columbite or tantalite concentrates. The interaction can, nevertheless, be discussed based on available information on the decomposition of lithium tantalate, LiTaC>3, and lithium niobate, LiNb03, using the hydrofluoride method [113,118,122]. 

Decomposition of lithium niobate, LiNb03, by molten ammonium hydrofluoride can be performed even at temperatures as low as 130-260°C [122]. The process also enables the separation of niobium and lithium, yielding ammonium oxyfluoroniobate and lithium fluoride. The interaction can be represented by Equation (132) ...
