Gips – razlika između verzija

 

'''Gips''' je vrlo mekan [[mineral]], po hemijskom sastavu '''[[kalcijum]] [[sulfat]] di[[hidrat]]''', CaSO₄•2H₂O. Anhidrovan prah [[kalcijumsulfat]]a, CaSO₄, kada se hidratiše, rekristališe i svara čvrstu masu koja se koristi u [[građevinarstvo|građevinarstvu]].

==Hemijski sastav==

<!--Heating gypsum to between 100°C and 150°C (302°F) partially [[dehydrate]]s the mineral by driving off exactly 75% of the water contained in its chemical structure. The temperature and time needed depend on ambient partial pressure of H₂O. Temperatures as high as 170°C are used in industrial calcination, but at these temperatures the anhydrite begins to be formed.

The reaction for the partial dehydration is:-->
