Results of the numerical simulation of dynamics of thermal-pressure stresses in a quartz particle under the non-stationary heating in a plasma flow are given. Peculiarities of dynamics of thermal-pressure stresses in the particle under condition of nonlinearity of thermal-physical quartz properties and phase transition of ?- to ?-quartz are revealed. The pressure component of the stress is analyzed and its links with temperature and with gas-liquid inclusions in vacuole are established. Conditions are determined under which the splitting of heated particles may take place.
