With the rise and development of glass-ceramic building materials, a new product known as glass-ceramic composite panels has appeared on the market. These panels are a layered combination of glass-ceramics and ceramic sheets, offering a wide range of benefits in terms of performance and application.
Firstly, glass-ceramic composite panels combine the best features of both materials. They benefit from the high mechanical strength, toughness, and impact resistance of glass-ceramics, while also inheriting the chemical resistance and durability of ceramic plates. As a result, these composite panels outperform pure glass-ceramic sheets in terms of mechanical properties and resistance to acids, alkalis, and other chemicals. This improvement not only enhances the overall performance of glass-ceramics but also allows for lighter panels, making them more suitable for use in high-rise buildings and large-scale construction projects.
Secondly, traditional production methods for pure glass-ceramic plates often involve manual polishing and intermittent firing processes using shuttle kilns or manually operated machines. This makes the process less efficient and more labor-intensive. In contrast, ceramic plate production typically uses highly automated and continuous production lines. The glass-ceramic composite panel is manufactured by placing glass-ceramic granules onto a pre-fired ceramic base and then firing it in a standard ceramic roller kiln. After that, it goes through an automated polishing line. This method enables continuous, mechanized, and automated production, significantly increasing output while reducing energy consumption—making it more aligned with modern industry standards for sustainability and efficiency.

Thirdly, the production of glass-ceramics involves expensive chemical raw materials and complex processing steps such as high-temperature melting, water quenching, drying, sieving, and crushing. These steps add to the overall cost. On the other hand, ceramic plates are usually made from natural raw materials and undergo a more straightforward manufacturing process, including ball milling, spray drying, forming, and firing. This makes ceramic production more cost-effective. The glass-ceramic composite panel combines a thin layer of costly glass-ceramic (about one-third of the total thickness) with a thicker, more affordable ceramic base (two-thirds of the thickness). As a result, the composite panel offers significant cost savings compared to pure glass-ceramic panels, making it a more economically viable option.
Since the introduction of microcrystalline glass-ceramic composite panels, over ten ceramic manufacturers have attempted to produce them. However, due to the high technical requirements and strict production conditions, many companies have struggled to maintain long-term production. Currently, there are fewer than ten manufacturers that have successfully scaled up production. Among them, Eurostar Micro-Crystals from Guangdong Gaoweijing Technology Co., Ltd. and Precision Gems from Guangdong Bode Seiko Building Materials Co., Ltd. stand out as leading brands in the high-end microcrystalline stone market. These companies were among the first to develop this technology, and they have accumulated over a decade of experience. Their products are known for their quality, consistency, and reliability, making them trusted choices in the industry.
