Enhancing the density of silicon carbide with the addition of nitrate-based additives [PDF]
Journal of Mining and Metallurgy. Section B: Metallurgy, 2022 Dense monolithic silicon carbide (SiC) was successfully sintered by hot pressing at 1750ºC for 1 h under an applied pressure of 20 MPa with the addition of a nitrate-based additive. With the addition of MgO-Y2O3 and Al2O3-Y2O3 in nitrate form, a relative

Optical properties of nanocrystalline Y2O3:Eu3+ [PDF]
Journal of Applied Physics, 2005 Optical properties of nanocrystalline red-emitting phosphor, europium-doped yttria (Y2O3:Eu3+), of average particle size of 15nm are investigated. The intensity of the strongest emission line at 612nm is found to be highest in the nanocrystalline sample with 4at.wt% of europium. The narrow electronic emission spectrum suggests a crystalline surrounding
