Abstract
A method for obtaining large burning monolithic titanium particles is described. The combustion of freely falling particles with a diameter of 120–540 \(\mu\)m in air at atmospheric pressure is investigated. The burning time and the characteristic beginning and end times of fragmentation as a function of particle diameter are determined by processing video recordings of combustion of more than 250 particles. Two fragmentation modes are described. It is found that the diameter of the burning particles determines which of these modes occurs. The boundary particle size separating the two modes is determined. It is shown that the fragmentation pattern and characteristic times for titanium agglomerates and monolithic particles of the indicated sizes differ slightly.
