Abstract

The invention discloses a nano bismuth oxide anti-radiation ceramic coating, and a preparation method and application thereof. The ceramic coating is formed by curing slurry of a characteristic coating prepared from, by mass, 10-25% of nano bismuth oxide; 20-30% of silane; 2-5% of acid; 45-60% of a solvent; and 1-5% of an auxiliary agent. The slurry of the characteristic coating is cured to form a ceramic coating, and the content of bismuth oxide in the ceramic coating can reach up to 80 wt%. The invention also discloses the preparation method of the ceramic coating. The preparation method comprises the following steps: preparing a characteristic coating, coating the surface of a tube shell substrate material with the characteristic coating, preparing a characteristic coating, and curing to obtain the ceramic coating. The invention further discloses the application of the ceramic coating. The ceramic coating is used for improving the radiation resistance of an electronic component base body, and damage to the electronic component base body by high-energy radiation such as gamma rays or X rays can be effectively reduced.

Description

technical field

[0001] The invention relates to the technical field of anti-radiation materials, in particular to a nano-bismuth oxide anti-radiation ceramic coating, a preparation method and an application. Background technique

[0002] With the development of aerospace technology and nuclear technology, the subsequent radiation safety issues are receiving more and more attention. The characteristics of radiation protection (irradiation) of microelectronic devices and optoelectronic integrated devices in harsh environments and Protection research is becoming more and more important. In the space environment, cosmic radiation is inevitable, and cosmic radiation can cause damage to microelectronic devices such as CPUs and optoelectronic integrated devices. The radiation effects of digital and analog integrated circuits in microelectronic devices are generally divided into total dose effects (TID), single event effects (SEE) and dose rate (Dose Rate) effects. Total dose effe...
