What is microcrystalline glass KK9? What's the difference from high alumina glass?

A: Microcrystalline Glass is a composite material formed by precipitating nanoscale microcrystalline particles in a glass matrix through specific heat treatment, combining the transparency of glass with the high strength of ceramics. KK9 is a microcrystalline glass product model of Nanshan Glass. The differences from high alumina glass: ① Strength: Microcrystalline glass, through nanocrystallization, has better bending strength and impact resistance than ordinary high alumina glass; ② Hardness: The Mohs hardness of microcrystalline glass can reach 6.5-7, while that of high alumina glass is approximately 6. ③ Toughness: Microcrystalline glass has better fracture toughness and is less prone to breakage. ④ Processing difficulty: Microcrystalline glass has high hardness, making cutting and hot bending more difficult and costly. ⑤ Thickness: Microcrystalline glass can be made thinner (0.25mm) while maintaining its strength. Woowhead Guanfudun Qu (launched in September 2026) is made of Nanshan Glass 'microcrystalline glass KK9, with a thickness of approximately 0.25mm. It features a 3D hot-bending process and is equipped with scinique® 2.0 technology. It is positioned higher than the current Guanfudun (Nanshan High alumina, 0.3mm). 2.5D) More advanced.
