    摘要: A method for forming a substrate for electronic applications having a dielectric constant of less than 6 is disclosed. The method comprises admixing crystalline cordierite particles having a size of 0.1--10 microns with a binder and solvent, casting the same into a sheet, drying the cast sheet into a self-supporting green sheet and then heating the green sheet to burn out the binder and to sinter the particles together. A metallization pattern is deposited on the green sheet after the casting but before the heating, the metallization pattern being molybdenum or tungsten. The cordierite has a defined coefficient of thermal expansion. A dielectric substrate for mounting of integrated circuit devices thereon is also disclosed.
