Ltcc composition having improved properties, manufacturing method of ceramic electric element using the same and ceramic electric element therefrom

A manufacturing method of a ceramic electric element using low-temperature co-sintering, comprising:

• forming a green tape from a slurry of an LTCC composition;
• disposing a metal electrode on at least one surface of the green tape;
• and
• co-sintering the green tape and the metal electrode at 650 to 950°C,
• wherein the LTCC composition includes
• a frit including silica and alumina;
• a first filler including at least one of silica and alumina;
• and
• a second filler including hexagonal boron nitride and having a granular shape.

A ceramic electric element obtained through low-temperature co-sintering, comprising:

• a ceramic substrate;
• and
• a metal electrode formed on at least one surface of the ceramic substrate,
• wherein the ceramic substrate includes a BN filler that includes hexagonal boron nitride and has a granular shape.
