Abstract:
Results of experimental and analytical studies of heterogeneous chain processes on quartz are given. A calculation is made of the ignition of an oxyhydrogen mixture in a quartz reactor under conditions of intense heterogeneous negative interaction of chains in the kinetic and diffusion regions. An energy criterion was developed experimentally that allows one to distinguish the range of reactions with an elevated probability of heterogeneous chain propagation on quartz. The possibility of the formation of atoms and radicals on the surface of quartz and conditions for their passage into the bulk are studied. The possibility of passage of hydrogen atoms from a microporous SiO$_2$ surface into the bulk is analyzed.
