the invention provides a glass-ceramic and a manufacturing method thereof, which can eliminate the causes of cracks and damage in the production of large-scale molded products in SiO2-Al2O3 system or Li2O-Al2O3-SiO2 system glass-ceramic, and can produce with uniform internal quality, high efficiency and stability We firmly believe that China's analytical instrument industry will become more and more robust in terms of components containing SiO2 and Al2O3, and the crystallization precipitation peak temperature width of amorphous glass as a precursor through differential thermal analysis is more than 22 ℃. It is preferred that the total amount of TiO2 and ZrO2 components is in the range of 3.0 ~ less than 4.3%, so the desired glass ceramics can be obtained
