摘要: Abstract This study reports the understanding of main features affecting microstructure and optical properties polycrystalline yttrium aluminum garnet (YAG) obtained by reactive sintering commercial micrometer-sized powders. Two shaping techniques, cold isostatic pressing slip casting, are studied samples at green stage related to behaviour during vacuum sintering, final transparency. The most promising results in terms transparency density were pressing, whereas high densities but a non-homogeneous particle packing inhibits pore closure thus limiting
