Condensed Products of Boron Combustion in Secondary Chamber

A experimental setup has been designed for boron particles ignition and combustion. A sampling system with sampling devices has been developed and used to collected condensed combustion products during the tests. The boron combustion products in different test axial locations were sampled and analysed by SEM, EDS and XRD. Agglomeration was formed during heating and combusting and became small while combustion in the secondary chamber. Three products of particles, squamas and protonemas presented orderly.
