· JVASP-49166· SnB4O7

Tin borate (SnB₄O₇) is a ceramic compound combining tin and borate phases, belonging to the family of metal borate ceramics. While primarily a research compound rather than a commodity material, tin borates are investigated for applications requiring thermal stability, chemical resistance, and specific electronic or optical properties inherent to borate glass-ceramic systems. The material represents an intermediate composition in the tin-boron-oxygen phase diagram, offering potential for specialized coatings, refractories, or functional ceramics where combined borate and tin oxide properties are advantageous.
