Compositions and quench products were identified optically and by X-ray. Limited solid solution of CaSO&lt;sub&gt;4&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;in K&lt;sub&gt;2&lt;/sub&gt;SO&lt;sub&gt;4&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;was found. There is a eutectic at 875°C and 34 wt. per cent CaSO&lt;sub&gt;4&lt;/sub&gt;. Calcium langbeinite melts incongruently at 1011°C. The melting-point of CaSO&lt;sub&gt;4&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;(1462°C) was determined by the quenching technique using sealed platinum tubes. The only intermediate crystalline phase found in the system is K&lt;sub&gt;2&lt;/sub&gt;SO&lt;sub&gt;4&lt;/sub&gt;·2CaSO&lt;sub&gt;4&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;(calcium langbeinite).&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</dc:description>
