FIELD: production of refractory paints (molded and non-molded) at roasting temperature up to 1550°C; marking articles before and after heat treatment.
SUBSTANCE: proposed dyestuff contains the following components, mass-%: titanium dioxide, 30-75; chromium oxide, 5-50 and cobalt aluminate, 5-40. Components taken at definite ratio (mass-%) make it possible to obtain dyestuff for marking the articles inclusive those working at high temperatures and keeping marks intact during operation at temperature up to 1550°C and at thermo-cycling of marked articles.
EFFECT: enhanced efficiency and reliability.
