FIELD: chemistry.
SUBSTANCE: transparent glassceramics contains the following components, mol %: SiO2 - 55-65; Al2O3 - 15-25; MgO - 15-25; Na2O - 0-1; K2O - 0-1; Li2O - 0-2.0; TiO2 - 8-12; CoO - 1.5-4.0; CeO2 - 2.0-6.0. Glassceramics contains crystalline phases: cobalt-containing aluminium-magnesium spinel, titanates and cerium silicates.
EFFECT: increase of thermo-mechanical stability and stability of coloring of IR-transparent glassceramics for colour filter, which has absorption of visual spectrum region and permeability in close to IR area of spectrum, to thermal shocks.
