Abstract
The mechanochemical formation of ZnS from a mixture of Zn and S powder s turns into a self-propagating thermal reaction after 30 min of milli ng. A similar ''explosion'' occurs when Sn and S are milled for about the same time to form SnS2. However, the ignition time is longer or th e reaction is gradual in mixtures of the two systems. This phenomenon is investigated as a function of composition. A model is proposed base d on the thermodynamic properties and mechanochemical reactions of the binary systems.
