Alumina-titania-zirconia fused grains (I) comprises alumina (10-50 mass.%), titania (10-40 mass.%), and zirconia (at higher than 50 mass.%), where the grain comprises monoclinic zirconia of higher than 98 mass.% and excludes titania phase. Independent claims are also included for the following: (1) a slide gate plate comprising a sintered composite material comprising (I); and (2) the production of (I) comprising mixing alumina, titania and zirconia to form a starting charge, fusing the charge to obtain a liquid, cooling the liquid for less than 3 minutes to form a solid mass, and optionally grinding the obtained solid mass to obtain a mixture of grains. |
