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...

Laoratanakul Engineering 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. 2018-09-10T03:42:00Z 2018-09-10T03:42:00Z 2008-12-01 Book Series 10226680 2-s2.0-62949242484 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=62949242484&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/60403
