titanium dioxide
noun
: the compound TiO2 that occurs naturally in three different crystal forms as rutile, anatase, and brookite, that is produced commercially from rutile or ilmenite as a white amorphous powder or in the rutile or anatase crystal forms, and that is used chiefly as a pigment or opacifier (as in paint, vitreous enamel, linoleum, rubber and plastics, printing ink, paper) because of its high covering power, brilliance and reflectivity, and resistance to light and fumes, and also in ceramic components for electronic equipment and in the form of large synthetic rutile crystals as gems |
