In recent years, researches on the chemical coating of glass and ceramic glass microsphere findings could change their optical and electrical properties and thermodynamic properties. In particular, can improve absorption and near-infrared reflectance of the electromagnetic wave after nickel, cobalt coating has been applied to military security, as the civilian technology only strengthen the performance of thermal insulation coatings.Other studies have loved incense activation method using silver nitrate cenospheres coated Ni-Co-P, can be used for electromagnetic shielding and microwave absorbing, the civilian aspects of the material can be made anti-electromagnetic radiation, military aspects can be made invisible absorbing material.
Co-density metal powder layer preparation Ling Guoping such as the use of chemical plating method, hollow glass beads coated with magnetic table, Co plating layer having excellent soft and hard magnetic properties. Sung-Soo Kim studied in the hollow ceramic beads plated metal layer of Co Fe magnetic and microwave absorption properties.
Studies show that adding metallized hollow ceramic beads of rubber to high-frequency electromagnetic and microwave absorption properties have. S.Shukla in fly ash particles and other surface copper plating, copper plating after the fly ash particles can be used as the conductive filler, for use in the polymer can be applied to an electromagnetic shield.
