Quali sono le proprietà meccaniche della vetroceramica microcristallina?

---

Vetro ceramico microcristallino (also known as glass ceramic or microcrystalline ceramic) is a high-performance composite material prepared by precisely controlling the crystallization process, combining the dual advantages of glass and ceramics. Its unique microstructure endows it with excellent mechanical properties, making it highly favored in high-end industrial, optical, electronic, and consumer goods fields. This article will objectively and professionally analyze the mechanical properties of microcrystalline glass ceramics, and explore their applications and advantages.

Overview of Mechanical Properties
The mechanical properties of microcrystalline glass ceramics are significantly better than ordinary glass and traditional ceramics, mainly reflected in the following aspects:
-High strength and high hardness: Through heat treatment, uniformly distributed fine crystals are formed, with a bending strength of up to 200-400 MPa, a Vickers hardness between 600-1200, and excellent wear resistance.
-Excellent impact resistance: The microcrystalline structure can effectively prevent crack propagation, and the fracture toughness (KIC) is usually 2-4 MPa · m ¹/², which is several times higher than ordinary glass.
-Basso coefficiente di espansione termica: The thermal expansion coefficient is close to zero, and it has excellent heat shock resistance. It is not easy to crack under severe temperature changes.
-Buona stabilità chimica: corrosion and oxidation resistance, maintaining stable performance in harsh environments.
