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

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] If traditional electronic functional ceramics want to achieve doping with organic polymer materials to improve their physical properties, low-temperature sintering technology is required to dope organic polymer materials such as inorganic compound matrix to form comp...
