Production of ammonium nitrohumate from Elbistan lignite and its use as a coal binder Yildirim, M; Ozbayoglu, G (1997-04-01) The conversion of Elbistan lignite into nitrogen-rich, alkali-soluble humic acid (ammonium nitrohumate) and its use as a coal binder were investigated. The optimum conditions for nitric acid oxidation and ammoniation were determined. The optimum HNO3 concentration was determined as 4.87 wt%. As a result, a humic acid solution containing 10.75 wt% nitrogen was obtained with 88.2 wt% recovery from Elbistan lignite. Coal-derived humic acid was used as a binder in briquetting of Tuncbilek lignite fines. It was ...

Production and identification of rare-earth doped lithium triborate Yılmaz, Ayşen; Ozdemir, Zeynep; Yılmaz, Aysun (2006-07-20) Research in the field of non-linear optical (NLO) devices lead to an increasing interest in new borate compounds, capable of expanding the frequency range provided by common laser sources. Lithium triborate (LBO) is a newly developed ideal non-linear optical crystal used in laser weapon, welder, radar, tracker, surgery, communication, etc. In this study, synthesis and identification of rare-earth doped lithium triborate was carried out. Borates containing rare-earth elements are of great interest since they...
