Keilhauite is a variety of the mineral titanite of a brownish black color, related to titanite in form. It consists chiefly of silicon dioxide, titanium dioxide, calcium oxide, and yttrium oxide. The variety was described in 1841 and named for Baltazar Mathias Keilhau (1797–1858) a Norwegian geologist. Keilhauite has a chemical formula of (CaTi,Al2,Fe3+2,Y3+2)SiO5. It differs from titanite only in that calcium is substituted by up to 10 percent (Y,Ce)2O3.
