Microcrystalline stone is called microcrystalline glass ceramic composite board in the industry. It is a high-tech product in the field of architectural ceramics. It is crystal clear, graceful and natural, and has different rhomboid textures and vivid colors. The decorative effect of the awe-inspiring work, as well as the pollution-free, easy-to-clean, intrinsic excellent physical and chemical properties, in addition to the weathering resistance stronger than the stone, the weather resistance of the early ceramic composite plate microcrystalline stone and the high-end building materials market at home and abroad. Favor.
Glass-ceramic, also known as glass-ceramic, is a novel phase-in-phase material for the microcrystalline phase and the glass phase. It is different from pure crystalline phase materials and a considerable portion of solid materials. Among these materials, the glass phase is usually small (more than a few), and the glass-ceramic, especially the glass-ceramic of decorative building materials, contains more glass phase (sometimes up to 50%). However, it is also much different from pure glass, which does not contain any crystalline phase under normal conditions, while microcrystalline glass contains a crystalline phase (mostly micron-sized microcrystalline phases). The biggest difference between the microcrystalline phase and the glass phase is that the particle is ordered in the internal structure of the former, and the particle is remotely disordered in the internal structure of the latter; the former produces diffraction lines by X-ray irradiation, while the latter Cannot produce diffraction lines.
Since glass-ceramic is a composite material of micro-crystals and glass phase, it has both certain properties of glass and some properties of crystals. Therefore, glass-ceramics concentrates on the characteristics of both glass and crystalline materials, including ceramic materials. The performance of this new type of composite material, glass-ceramic, depends on the type of microcrystalline phase inside it, the size and distribution of the crystal, and the amount, composition, and structure of the remaining glass phases. Therefore, glass-ceramics not only have a small coefficient of thermal expansion (which can be an excellent thermal shock-resistant material), but also have high hardness, wear-resistant mechanical properties (which can be high-strength materials), and can also have special Electrical, thermal, optical, magnetic, biological properties (this becomes a functional material). Therefore, glass-ceramics can be used in many fields.
Polishing line for producing microcrystalline stone
In the field of building materials, since the Soviet Union invented the calendering method to prepare glass-ceramics in the 1960s and later invented the method of preparing glass-ceramic building decoration materials by sintering in Japan, this material has its high-grade decorative art and excellent machinery. Performance, chemical resistance (weathering weathering), extensive source of raw materials and low economic costs have gradually entered the high-end building materials market. Today, this glass-ceramic building material has been hailed as "the high-end decorative material of the 21st century."
