YSZ exhibits a unique mechanism known as "transformation toughening." When stress induces micro-cracks, the tetragonal crystal phase transitions to a monoclinic phase, expanding volume by 3-5% and effectively compressing the crack tip closed. This results in double the flexural strength and significantly higher fracture toughness compared to standard alumina.
Aluminium Titanate (Al2TiO5) possesses an extremely low coefficient of thermal expansion (<1.5 × 10-6/K) and high thermal shock resistance. Crucially, molten aluminum does not wet or adhere to its surface, preventing oxide buildup inside riser tubes and extending component life compared to cast iron or silicon carbide options.
Through our state-of-the-art 5-axis CNC diamond grinding and surface lapping facilities, we routine achieve outer/inner diameter tolerances down to ±0.001mm, surface roughness Ra ≤ 0.05μm, and flatness within 0.0005mm, verified by CMM inspection certificates.
