References section at the end of main body content edit

Currently the main content of this article ends in a references section that lists these 3 different sources: Structure and Characterization of Lithiumaluminalsilicate Glass and Glass Ceramics derived from Spodumene Mineral. A. Nordman, Y Cheng, T.J. Bastock, Journal of Physics Condensed Matter, Volume 7, Number 16 Glass-ceramics capture $2 million telescope-mirror contract. David H. Taeler, Ceramic Age, August 1968, Volume 84, Number 8 Transparent Glass-Ceramics G. H. Beal, D. A. Duke, Journal of Materials Science 4(1969) 140-152

Not sure how to fix this, and the article content will need to be marked with sources as well. It seems like only the Applications section is properly cited.
