These ceramic objects made from forsterite ceramic have coefficient of heat expansion comparable with the one of glass. However, ceramics and glasses are two different materials, therefore, the process of annealing must be long enough and precise to remove all the stress in the product.
EXAMPLE
The following example illustrates the invention. It is given for illustration only and not be understood to limit the scope of invention in any way.
Grafting ceramic objects into glass
The glass being used to form plate glass is lime alkali glass with coefficient of heat expansion oc = 85 — 95 x 10"7 x 0C at 4000C. Chemical composition of the glass and the ceramic are shown in the Table 1.
Depending on the thickness, dimension and shape of the product, the ceramic objects to be grafted into glass will be formed by way of pouring, rolling plastic mixture or semi-dry pressing of mixed materials. With thickness of plate glass is < 10mm, thickness of ceramic is < 5mm.
If the ceramic object having the thickness of < 2 mm, it will be formed by way of rolling plastic mixture with suitable wetness (from 15 percent to 25 percent) or way of semi-dry pressing if the wetness of the mixed materials is of 5-15%.
If the ceramic object having the thickness of from 2 to 5mm, it may be formed by way of pouring, rolling plastic mixture or semi-dry pressing depending on the shape of the product.
After being formed, the product is pre-heated at 850°C, drawn, glazed and finally heated at 12000C to obtain ceramic objects with coefficient of heat expansion at 4000C of 85 ± 3 x 10"7 x 0C1.
Glass being melt at 1500 ± 500C in the tank furnace with refractory float and throttle valve is pulled by forming machine. During pulling up the glass, the spreader will evenly spreads ceramic objects on the surface of glass. As a result, the ceramic things are distributed evenly in the entire plate glass. Then, in the process of annealing, the temperature of glass is gradually coolled to the ambient temperature to remove all the stresses and avoid defects in the product. After annealing, the product is cut and cleaned unnecessary edges or grinded and polished to improve on.
After being manufactured, the plate glass is checked for technological parameters and defects such as flatness, roughness, crack, etc...
