In order to preserve a spherical granule shape in a porous sintered body, presintering technology was developed to enhance the strength of Si-mixture granules containing Y 2 O 3 –Al 2 O 3 –CaO as sintering additives prior to shaping. The fracture

Porous sintered reaction-bonded silicon nitride ceramics with dual-sized pore channels were fabricated using granules consisting of a Si-additive. A pressureless tapping method was used to maintain the spherical morphology of the weak spray-dried gra

The spectral variation of Y3Al5O12:Ce3+ (YAG) with temperature is smaller than that of its alternative (Ba, Sr) 2SiO4:Eu2 (BOS). The quenching temperature of YAG is higher than that of BOS. On the other hand, the luminance of YAG is seriously thermal
