Abstract
The particle growth of ZnS: Cu, Al phosphor during firing has been investigated in order to obtain information about the effects of fluxing additives on the growth mechanisms. When type-I fluxes (MgCl2, CaCl2 and NaCl) are used, the particle size increases rapidly in the early stages of firing, and saturates when the firing time is increased further. Type-II fluxes (CsCl, KCl, KI and NaI) induce a further large increase in the particle size after a plateau period following the initial growth. The optimum quantities of fluxes to facilitate the particle growth most effectively are in the region of several tenths of a mol% to several mol%. The particle growth mechanisms are discussed using the theory of sintering.Keywords
