Notes:
Interactions between BeO substrates and high-lead glasses of typical composition for hybrid thick films have been studied by means of secondary neutral mass spectrometry. The Be atomic concentration on top of glass layers, 2–40 μm thick, prepared at various temperatures Tf, ranging from 750 to 1000 °C have been measured. The results give insight of Be solubility values from 0.5 to about 6 at. %, according to the glass type and firing temperature, and diffusion coefficients higher than 10−10 cm2/s. Moreover, the diffusion mechanism appears quite different from that involved in interactions between the same glasses and alumina substrates, since no correlated diffusion process has been observed in the present case.
