Ceramic material has a low dielectric constant, the structure has the green, and ceramic material sintered which is obtained

摘要

A ceramic material having a dieiectric constant of less than 6 when measured at 1 MHZ is formed by preparing a green structure composed of foam and alumina having a surface area of 20Mz/g and glass frits powder. A laminate of three 1.016mm layers of the green structure is then sintered in air at about 920 DEG C to gild the ceramic material.
