Abstract

The invention relates to a novel X-ray radiation protective ceramic material which is made by evenly blending fine-grain-shaped ray absorbing substance with ceramic raw materials and then sintering at a high temperature. The novel X-ray radiation protective ceramic material is characterized in that the absorbing substance is mainly made of heavy elements such as lead, tungsten, copper and rare earth or compound of these heavy elements. Accordingly, the ceramic material has high X-ray protection capacity and is applicable to X-ray protection of equipment such as accelerators, ion sources and X-ray machines.

Description

technical field [0001] The invention relates to a protective material for X and gamma rays and a preparation method thereof, and belongs to the technical field of radiation protective materials. Background technique [0002] X-ray equipment produced by ion sources, accelerators, implanters, X-ray machines, CT, etc. often require ceramic insulators to isolate metal parts at different potentials. The usual ceramics have poor absorption of X-rays and cannot play an effective role. radiation protection. There are usually strong high-voltage electric fields inside ion sources, accelerators and other equipment, so specific radiation protection measures are often required to reduce the escape of X-rays. The ceramic material of the invention has strong radiation protection ability and insulation performance, and the ceramic material made by the invention can play the role of X-ray protection, which is of great help to the simplification of the structure of the X-ray generating equi...
