FIELD: process engineering.
SUBSTANCE: invention relates to production of luminescent ceramic converter. Proposed method comprises the steps that follow. (a) Integration of precursor material with ore-forming admixture to get raw mix. Note here that ore-forming admixture comprises, in fact, spherical particles of carbon or organic material. (b) Moulding raw mix to make raw billet of ceramic converter. (c) Heating of raw billet to remove ore-forming admixture and to form pre-calcined ceramic material with, in fact, spherical pores. (d) Sintering of pre-calcined ceramic material to form luminescent ceramic converter. Proposed luminescent ceramic converter comprises sintered monolithic ceramic material converting light with first wavelength in light with second wavelength. Ceramic material has, in fact, spherical pores with mean size of 0.5-10 mcm.
EFFECT: controlled distribution of pores and pore sizes on luminescent ceramic converter.
