Abstract
The possibility of using waste of semiconductor manufacturing containing silicon carbide and gallium arsenide as an effective additive in radio absorbing material preparation was established as a result of research. The resulting material meets the requirements of effective porous electromagnetic radiation absorbers of extremely high frequency range: maximum absorption and minimum reflection of electromagnetic radiation, fire safety, the minimum allowable level of toxic and hazardous substances.
Highlights
The relevance of research on the porous glass composites creation due to the demand for radio absorbing materials with improved characteristics that differ from their counterparts in environmental and fire safety
The particles of crystalline phase with high dielectric and magnetic permeability, give to material ability to absorb electromagnetic radiation. Such materials been used as radio absorbers of electromagnetic radiation of extremely high frequency range in various areas: shielding of premises, protection of mobile objects from detection, when detecting dangerous objects and substances
The aim of the work is to develop a porous glass composite modified with silicon carbide and gallium arsenide at temperatures not exceeding 400 °C, which has a high radio absorbing ability in the extremely high frequency range
Summary
The relevance of research on the porous glass composites creation due to the demand for radio absorbing materials with improved characteristics that differ from their counterparts in environmental and fire safety. The particles of crystalline phase with high dielectric and magnetic permeability, give to material ability to absorb electromagnetic radiation. The requirements of functional properties for this material such as high absorption coefficient and low reflection coefficient of electromagnetic radiation, as well as reduced density and increased mechanical strength. Achieving these properties increases the material efficiency and has great prospects, but it is rather difficult to implement in practice, it is of scientific interest for researchers
