Embodiment Construction
[0098] Table 1 lists the final composition and sintering temperature of various glasses produced according to the sintering process.
[0099] Table 1
[0100] Example
[0101] Shown is the amount of dopant added to the matrix glass.
[0102] Table 2 shows the same glass as in Table 1, except that the dopant is CdSe. The same matrix glass is indicated by the same number. It should be noted that the amount of doping depends on the dopant. Its sintering temperature is equivalent to that described in Table 1, so it is not listed in Table 2.
[0103] In order to improve the quality of the glass, especially to reduce the number of bubbles, it is best that the glass not only reach the sintering temperature, but the temperature should be increased. This reduces the viscosity of the glass and allows the generated bubbles to escape the glass body.
[0104] The difference from Table 1 is that the temperature of the examples is listed in Table 2, at which all bubbles contained in th...
