  • Ceramic composition
    Patent number: 10800967
    Abstract: Provided is a ceramic composition capable of achieving a light scattering function while maintaining optical properties at a high level. The ceramic composition comprises a fluorescence phase comprising a fluorescent material and a light-scattering phase comprising a lanthanum oxide. The lanthanum oxide may be, for example, at least one selected from LaAlO3 and La2O3. The ratio of the fluorescent material (or the fluorescence phase) to the lanthanum oxide (or the light-scattering phase), the former/the latter, may be 99.9/0.1 to 50/50 in terms of volume ratio.
