Sonocatalyzed ammonothermal preparation of fine lithium niobate powders

The so-called sonocatalyzed ammonothermal technique has been developed for the preparation of lithium niobate fine powders from commercially as-received niobium pentoxide and lithium nitrate. The present work shows that the application of ultrasonic activation prior to the ammonothermal treatment ca...

The so-called sonocatalyzed ammonothermal technique has been developed for the preparation of lithium niobate fine powders from commercially as-received niobium pentoxide and lithium nitrate. The present work shows that the application of ultrasonic activation prior to the ammonothermal treatment can produce a single phase lithium niobate fine powder at a relatively low temperature of 220°C. The influences of Li-precursors, ammonia solution concentration, reaction temperature and time, as well as Li:Nb mole ratio - which is evidentially the most critical factor promoting a single phase formation - are discussed. © 2008 Trans Tech Publications, Switzerland. 2014-08-30T02:56:28Z 2014-08-30T02:56:28Z 2008 Conference Paper 9780878493562 10226680 75596 http://www.scopus.com/inward/record.url?eid=2-s2.0-62949242484&partnerID=40&md5=74df71a752f3aa3abbf78e170da0e39e http://cmuir.cmu.ac.th/handle/6653943832/5379 English
