Claims18
A solid composite material combining:
- an inorganic pigment in the form of discrete particles each comprising a colored core and a coating surrounding the core, said coating being adapted to allow light to pass through;
- and
- a matrix based on metalloid or metal oxide, said matrix being adapted to allow light to pass through.
A method for producing a solid composite material according to any preceding claim, said method comprising the following steps:
- a) selecting an inorganic pigment in the form of discrete particles each comprising a colored core and a coating surrounding the core, said coating being adapted to allow light to pass through;
- b) mixing the inorganic pigment in powder form with the matrix in powder form;
- and
- c) sintering said powder mixture.
