CERAMIC RAW MATERIAL COMPOSITION, CERAMIC SUBSTRATE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a ceramic raw material composition capable of being simultaneously sintered with a low-melting metal such as silver and copper and having excellent electric characteristics in a high-frequency range such as GHz zone and having high strength and to provide a ceramic substrate and its manufacturing method. SOLUTION: The ceramic substrate is prepared by using the ceramic raw material composition containing 0.5-3 pts.wt. lanthanum oxide and 0.5-3 pts.wt. magnesium oxide to 100 pts.wt. main component consisting of 80-90 wt.% forsterite and 10-20 wt.% calcium titanate and containing 0.5-4 pts.wt. lithium fluoride to 100 pts.wt. forsterite, calcium titanate, magnesium oxide and lanthanum oxide.
