[China Glass Net] Microcrystalline glass is also known as microcrystalline jade or ceramic glass. Mainly used in induction cookers, high-power induction cookers and other products. It is a comprehensive glass, and its scientific name is glass ceramic. The glass to which a specific combination of crystal nucleating agents is added is subjected to crystallization heat treatment under controlled conditions (certain temperature) to become a composite material having a uniform distribution of microcrystals and a glass phase.
Glass-ceramics and our common glass look very different. It has the dual characteristics of glass and ceramic. The atomic arrangement inside the ordinary glass is not regular, which is one of the reasons for the fragility of the glass. Microcrystalline glass, like ceramics, consists of crystals, that is, its atomic arrangement is regular. Therefore, the reason why the glass-ceramic glass is higher than the brightness of the ceramic, and the glass toughness is stronger than that of the glass-ceramic. The main reason for using the glass-ceramic is that the glass-ceramic has high mechanical strength, excellent insulation performance, low dielectric loss, and stable dielectric constant. The coefficient of thermal expansion can be adjusted in a wide range, chemical corrosion resistance, wear resistance, good thermal stability and high use temperature.
Planar glass-ceramics are currently widely used in stoves for household induction cookers. Concave-ceramic glass-ceramics refer to glass-ceramics that are concave in shape and resemble the current state of the pot. The main use of the glass-ceramic plate is currently mainly used in high-power commercial induction cookers. With the increase in gas prices, the cost of the catering industry, and the perception of cooking without open flames, the number of commercial induction cookers has increased. The demand for concave glass-ceramics will also increase accordingly.
The conventional micro-ceramic plates used in commercial induction cookers have the following dimensions: 250×250mm, 300×300mm, 350×350mm, 450×450mm, 500×500mm, 600×600mm, etc., and the common thickness is 12-20mm.
The conventional dimensions of the concave glass ceramic used in the commercial induction cooker are: diameter 200 mm, diameter 300 mm, diameter 400 mm, diameter 500 mm, and the like.
