Background
Glass ceramic is also called microcrystalline glass and microcrystalline ceramic, and is a polycrystalline solid phase material containing glass body, which is prepared by performing controlled nucleation and crystallization on base glass with certain specific compositions at a certain temperature. The properties of glass ceramics are mainly determined by the main crystal phase, which can be achieved by controlling nucleation, crystallization and selecting different mother glass components. Glass ceramics have the characteristics of both glass and ceramics, are superior to metals and polymers in terms of thermal, chemical, biological, optical and electrical properties, and the composition and microstructure are two main influencing factors of the design of glass ceramic components, the main component is a decisive factor for nucleation, and for glass ceramics with mechanical and optical properties, the microstructure is a more critical influencing factor, and different heat treatment systems can have important influence on the microstructure in relation to the aggregation of the main component and microcrystals. Nucleation is a determining factor in controlling crystallization. The formation of crystals in the mother glass generally proceeds through two stages: (1) a sub-micronuclei formation stage; (2) sub-micronucleus growth stage. The two phases are referred to as nucleation and crystal growth, respectively. Nucleation is affected by two factors: (1) selecting mother glass with proper chemical composition, and adding a certain nucleating agent; (2) and controlling a heat treatment system, namely heating temperature and heat preservation time.

TABLE 1 results of glass-ceramic 1-3 Performance test
| Numbering device | Flexural strength (MPa) | Vickers hardness (MPa) |
| 1 | 365 | 1125 |
| 2 | 284 | 905 |
