· JVASP-11668· Cr2SiO4

Chromium silicate (Cr₂SiO₄) is a ceramic compound combining chromium oxide and silica, belonging to the family of transition metal silicates. It is primarily investigated as a refractory and high-temperature material, with potential applications in extreme thermal environments where chemical stability and oxidation resistance are critical. This material is notable in research contexts for thermal protection systems and specialized industrial furnace linings, though it remains less common than established refractories like alumina or magnesia-spinel composites.
