550°C

Table 1 shows the conditions of the calculation. Five cases are assumed and calculated These • have different conditions of sealant material, glass arrangement and constraint temperature. Case 1 and case 2 have no glass sealant and are different in the constraint temperature. Case 3 and case 4 have different glasses, and case4 and5 have different glass arrangement. As sealant, two types of glass ate assumed The glass 1 is the borosilicate glass. The glass 2 is the soda-lime glass in which fine alumina powderis dispersed to control its viscosity. The thermal expansion coefficient(TEC) and other
