  <dc:description>&lt;p&gt;&lt;span&gt;The decarbonation curve for ZnCO&lt;/span&gt;&lt;sub&gt;3&lt;/sub&gt;&lt;span&gt;&amp;nbsp;has been determined in the pressure range 3–20 kbar by using a combination of cold-seal vessels and piston-cylinder apparatus with NaCl assemblies. Heat capacities for both synthetic and natural ZnCO&lt;/span&gt;&lt;sub&gt;3&lt;/sub&gt;&lt;span&gt;&amp;nbsp;samples were measured by differential scanning calorimetry at temperatures ranging from 340 to 497 K. The results of these experiments indicate that the enthalpy of formation for smithsonite,&amp;nbsp;&lt;/span&gt;&lt;i&gt;ΔH&lt;/i&gt;&lt;sub&gt;&lt;i&gt;f&lt;/i&gt;&lt;/sub&gt;&lt;span&gt;(1,298.15), is approximately −817. kJ/mol. which is about 4 kJ more negative than most tabulated values.&lt;/span&gt;&lt;/p&gt;</dc:description>
