There has been intense activity over the last three decades in the area of preparation of various ceramic materials using synthetic or natural zeolites as a precursors. Aqueous ion exchange can be preformed to incorporate a variety of other metals, typically alkali and alkaline earth for the Rn+ cation. For this investigation was used the two naturale HEU type zeolite from different deposit. Thermally induced phase transformation of Pb, Ca and K-exchange is followed in the range from room temperature to 1300 ºC. The frameworks collapse into amorphous intermediate products after heating between 600 and 650 °C. Prolonged heating of the intermediate product over 900 °C results directly in formation of alumosilicate phases anorthite or structure of celsian. The crystale phases of alumosilicate in temperature range between 700 and 1300 °C was investigated by X-ray powder analyses.
