· JVASP-9481· MgTiSiO5

MgTiSiO5 is a magnesium titanium silicate ceramic compound that combines properties from multiple oxide systems, placing it in the family of complex ternary oxide ceramics. While not a widely commercialized material, this composition is of research interest for applications requiring a blend of thermal stability, moderate stiffness, and lightweight performance inherent to magnesium-titanium ceramic systems. Its potential lies in high-temperature structural applications where the synergistic effects of titanium oxide (thermal stability) and magnesium silicate (low density, refractoriness) can provide advantages over single-phase alternatives.
