WCoB-TiC ceramic composites with various initial Co content (varying between 10wt% and 47wt%) were fabricated by liquid phase reaction sintering (LPRS) in a vacuum furnace. The microstructure, hardness, transverse rupture strength (TRS) and high-temperature oxidation resistance of WCoB-TiC ceramic composites were investigated. The results revealed that initial Co content had an important influence...
Eu 3+ -activated MgAl(PO 4 )O:phosphor has been synthesized by a high temperature solid state reaction and efficient red emission under near-ultraviolet excitation is observed. The emission spectrum shows a dominant peak at 594nm due to the 5 D 0 → 7 F 1 transition of Eu 3+ . The excitation spectrum is coupled well with the emission of UV LED...
