Problems solved by technology

Although this method can realize inorganic-organic compounding, there are many types of components, and it is difficult to precisely control the formula ratio in industrial production, resulting in poor performance uniformity and low yield of final ceramic products.
Secondly, some of the inorganic compounds and organic polymer materials used are expensive, which is not conducive to cost control in the industry

Abstract

The invention discloses an organic acid salt electronic functional ceramic and its manufacturing method and application. Acid-based organic acid salts, formic acid-based organic acid salts, acetic acid-based organic acid salts, or gluconic acid-based organic acid salts. A single organic acid salt powder is used for sintering, the pressure load during sintering is 150MPa-350MPa, the sintering temperature is 20-300℃, the heating rate is 10-15℃ / min, and the sintering time is 40-150min. After sintering, we get Organic salt electronic functional ceramics with density ≥ 95%. Application of organic acid salt electronic functional ceramics in varistors, microwave dielectric ceramics and magneto-dielectric coupling ceramics. On the premise of reducing the difficulty and cost of the process, the electronic functional ceramics with remarkable DC voltage-sensitive characteristics or excellent microwave dielectric properties are obtained.

Description

technical field [0001] The invention belongs to the application field of power electronics and electronic information, and relates to an electronic functional ceramic and its manufacturing method and application. Background technique [0002] Due to their own physical properties, such as: acoustic, optical, thermal, electrical, magnetic and mechanical properties, electronic functional ceramics are widely used in the fields of electronic information, microelectronics, and Internet of Things sensors. Traditional electronic functional ceramics are prepared from one inorganic compound or dense composite ceramic materials are prepared from multiple inorganic compounds through different processing techniques. [0003] In order to improve the physical properties of traditional electronic functional ceramics by doping organic polymer materials, low-temperature sintering technology is required to dope organic polymer materials such as inorganic compound matrix to form composite ceram...
