Abstract

 Petrography, XRD and DTA- TG studies indicate that SERPENTINE decomposition to FORSTERITE in high temperature. SERPENTINE has been expanded in Iranian ophiolitic rocks. Testing Iranian ophiolitic rocks shows that FORSTERITE has been produced from heating of SERPENTINE in 600 °C. Therefore it facilitates the usage of serpentinic rocks as primary material in REFRACTORY industry. The test results show that, Dehydration reactions on SERPENTINE started at approximately between 100 to 150 °C and dehydroxilation reactions started at approximately 550-700°C. As a result of thermal reaction the decomposition of SERPENTINE will take place and then changing in to olivine (FORSTERITE). Crystallization of olivine (FORSTERITE) will start at 600 °C.
