Problems solved by technology

[0003] The traditional glass-ceramic production mostly adopts the sintering process. The high energy consumption of the sintering process in the production of glass-ceramics has always been a key bottleneck restricting the rapid development and large-scale production of glass-ceramics.
The production of glass-ceramic by sintering process and the use of expensive non-ferrous metal zinc oxide raw materials have kept the production cost of many glass-ceramic enterprises at a high level. At the same time, the production process efficiency of sintering method is low, and the products have pores and poor flatness. , sintering process glass-ceramic enterprises operating conditions have always been difficult
