Joining by glasses glazing

Inorganic glasses based on SiC 2 can be used to produce joints between metal or ceramic components by glazing, the inorganic analogue of brazing. 

Some of the glassy silicate materials cited in Table 9.1 have been used as joining materials in laboratory studies but most are unsuitable for realistic applications. Thus the Na and K silicates are soluble in water and hence unsuitable 

As shown in Chapter 9, glasses can wet and wet well a wide range of ceramic and metallic components and that, therefore, predictions of the extent of capillary flow (equations (10.1) and (10.2)) can make use of the approximation that cos0 is equal to 1. However, these penetrations are not achieved instantly and the main ratedetermining material characteristic is the crLV/ ) ratio, which is much smaller
