CERAMIC COATED METAL SUBTRATES FOR ELECTRONIC APPLICATIONS

摘要

The present invention is directed to a ceramic (16) coated metal (12) substrate having improved processibility characteristics in the manufacture of electronic devices, as for example electronic circuits, and to processes for manufacture of such devices. The coating is made of a glass/ceramic comprising (on an oxide basis and based on on the total weight of the coatings): (a) from about 8 to about 26% by weight of magnesium oxide (MgO); (b) from about 10% to about 49% by weight of aluminum oxide (Al2O3); and (c) from about 42 to about 68% by weight of silicon oxide (SiO2). The main crystalline phase is cordierite.
