Bu çalışmada başlangıç maddesi olarak kolemanit ve diamonyum hidrojen fosfat bileşikleri kullanılmıştır. Uygun mol oranında ve çeşitli sıcaklıklarda (700, 800, 900, 1000, 1100 ve 1200 0C) gerçekleştirilen reaksiyonlar ile CaBPO5 bileşiği elde edilmeye çalışılmıştır. Karakterizasyon çalışmaları, X-ışınları toz kırınımı ve FTIR spektroskopisi ile gerçekleştirilmiştir. Yapılan deneyler sonucunda 1000 0C’ de bu bileşiğin iyi bir kristallenme ile sentezinin yapılabileceği ve kolemanit’in sıcaklıkla yapısal değişiminin sentez ile ilişkili olduğu belirlenmiştir

The Investigation of Structural Changing of Colemanite With Temperature and Solid-State Synthesis and Characterization of Cabpo5 Using Colemanite

Öz

In this study, different temperatures (700, 800, 900, 1000, 1100 ve 1200 0C) and appropriate molar ratio were used to determine optimum temperature. We synthesized CaBPO5 using colemanite and diamonium hydrogen phosphate at 1000 C. Crystal structure is characterized by powder X-ray diffraction and FTIR spectroscopy. The structural changing of colemanite with temperature is related to synthesis of CaBPO5
