Abstract

The invention provides a ceramic composition which comprises the following components in parts by weight: 60-70 parts of barium titanate, 20-30 parts of barium zirconate, 5-10 parts of strontium titanate, 2-5 parts of calcium titanate, 2-5 parts of calcium zirconate, 5-10 parts of polyester fibers, 5-10 parts of glass fibers, 5-10 parts of coal gangue powder, 5-10 parts of grass carbon and 5-8 parts of sintering additives. The dielectric ceramic composition has the advantages of uniformity in dielectric constant and dielectric peak value higher than 11000 at room temperature.

Description

technical field [0001] The invention relates to a ceramic composition and a preparation method thereof. Background technique [0002] With the advancement of wireless communication technology, the demand for portable mobile communication products has also increased significantly, and is developing towards thinner and smaller size, high reliability and low price, so as to meet the requirements of miniaturization and lightweight high-density construction. Since wireless communication products use microwaves to transmit signals, the ceramic materials used must have a high dielectric constant (εr) and a high quality factor (Q×f) at room temperature. [0003] In China Taiwan Patent Publication No. 373201, a dielectric ceramic composition is disclosed, comprising (BaCa)TiO 3 As the main component, manganese carbonate (MnCO 3 ), dysprosium trioxide (Dy 2 o 3 ), niobium pentoxide (Nb 2 o 5 ) as a secondary component. Although the dielectric ceramic composition can reach a die...
