Currently, it makes microwave radar, infrared, radar or other electromagnetic wave radar and acoustic detection system shield absorbing materials have been widespread concern in the military field.

Near infrared reflective material can be used in aviation, aerospace, building materials, vehicles, weapons and other fields. Cenospheres powder density is small, the metal surface after its treatment, can be substituted for the denser metal electromagnetic wave absorbing powder (RAM) or prepared electromagnetic shielding (EMI) material.

In recent years, researches on the chemical coating of glass and ceramic hollow beads 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.
