Impact of starting alumina powders on densification peculiarities of reactive-sintered YAG:Sm3+ ceramics
YAG:Sm3+ (5 at.%) transparent ceramics have been obtained by reactive sintering using different starting Al2O3 powders. Effect of particle size in the 100–400 nm range, morphology and dispersity of starting alumina powders on the properties of YAG:Sm3+ powder mixtures, their densification and result...

| description | YAG:Sm3+ (5 at.%) transparent ceramics have been obtained by reactive sintering using different starting Al2O3 powders. Effect of particle size in the 100–400 nm range, morphology and dispersity of starting alumina powders on the properties of YAG:Sm3+ powder mixtures, their densification and resulted optical ceramics have been studied. It was shown that YAG:Sm3+ powder mixtures prepared with BMA15 and AKP-50 powders possess significant reduction of a fraction of micron-sized agglomerates. The particles within the range of 100–300 nm presented in BMA15 and AKP-50 powders, act as proppant, enabling collapse of the Y2O3 agglomerates. As a result, ceramics prepared from these powder mixtures show improved densification behavior. Reactively-sintered YAG:Sm3+ transparent ceramics prepared using AKP-50 powder are characterized by optical transmittance of 83% and low concentration of residual pores. |
