A high-temperature Guinier camera and its application to the decomposition of Co_1-xS (jaipurite)

A high-temperature Guinier camera for closed and open systems used for temperatures up to 1170 K is described. As an exemplary application the decay of Co_{1 - x}S (jaipurite) to Co₃S₄ (linnaeite) and Co₉S₈ (Co-pentlandite) at 663 and 723 K under its own vapour pressure is presented.
