    <subfield code="a">&lt;p&gt;In this research, copper borates are synthesized by the&lt;br&gt;
reaction of copper sulfate pentahydrate (CuSO4.5H2O) and&lt;br&gt;
tincalconite (Na2O4B7.10H2O). The experimental parameters are&lt;br&gt;
selected as 80oC reaction temperature and 60 of reaction time. The&lt;br&gt;
effect of mole ratio of CuSO4.5H2O to Na2O4B7.5H2O is studied. For&lt;br&gt;
the identification analyses X-Ray Diffraction (XRD) and Fourier&lt;br&gt;
Transform Infrared Spectroscopy (FT-IR) techniques are used. At the&lt;br&gt;
end of the experiments, synthesized copper borate is matched with&lt;br&gt;
the powder diffraction file of &amp;ldquo;00-001-0472&amp;rdquo; [Cu(BO2)2] and&lt;br&gt;
characteristic vibrations between B and O atoms are seen. The proper&lt;br&gt;
crystals are obtained at the mole ratio of 3:1. This study showed that&lt;br&gt;
simplified synthesis process is suitable for the production of copper&lt;br&gt;
borate minerals.&lt;/p&gt;</subfield>
