Tempered glass is a specially treated glass material with excellent impact resistance, heat resistance, cold resistance, and explosion-proof properties. This material is not only lightweight and has good light transmittance, but also hard, making it ideal for induction cooktop panels. During cooking, users can clearly observe the changes in food, and its excellent high-temperature resistance can meet the high-temperature environment of induction cooktops. Furthermore, the smooth surface of tempered glass makes cleaning simple and convenient, effectively preventing stains.
Besides tempered glass, ceramic glass is also chosen by some induction cooktop manufacturers as a panel material. Ceramic glass is favored for its hardness, high surface smoothness, and resistance to high temperatures and acid/alkali corrosion. These characteristics make ceramic glass perform well in induction cooktop applications, especially its high-temperature resistance, which can withstand the high temperatures of induction cooktop operation.
However, both tempered glass and ceramic glass have certain drawbacks. Compared to metal, glass is relatively weak and fragile. During use, it is easily broken if it comes into contact with sharp objects or is subjected to external impact. In addition, the cost of these two materials is relatively high, thus affecting the overall price of the induction cooktop.
It is worth noting that a new type of induction cooker panel material has emerged on the market-microcrystalline glass. Microcrystalline glass is not only aesthetically pleasing and easy to clean, but also has higher high-temperature resistance and impact resistance, which is expected to further extend the service life of induction cookers.
