Growth of high quality NLO material

361-363<span style="font-size: 15.5pt;mso-bidi-font-size:8.5pt;font-family:" times="" new="" roman","serif""="">The melastable zone width studies have been carried out using Imol % of EDTA in ammonium dihydrogen orthophosphate (A DP) solution. It has been round that the zone width is enhanced significantly <span style="font-size: 13.0pt;mso-bidi-font-size:6.0pt;font-family:HiddenHorzOCR;mso-hansi-font-family: " times="" new="" roman";mso-bidi-font-family:hiddenhorzocr"="">at all experimental temperatures  and the multi  <span style="font-size:13.0pt; mso-bidi-font-size:6.0pt;font-family:HiddenHorzOCR;mso-hansi-font-family:" times="" new="" roman";="" mso-bidi-font-family:hiddenhorzocr"="">nucleation <span style="font-size: 15.5pt;mso-bidi-font-size:8.5pt;font-family:" times="" new="" roman","serif""="">is reduced considerably.
