ECCOSTOCK® HiK Powder - Free Flowing Dielectric Powders

• ECCOSTOCK® HiK Powder is a is a series of granular, free flowing powders of adjusted dielectric properties
• Though these standard powders are extremely low loss, materials of moderate and high loss can be supplied on special order
• ECCOSTOCK® HiK Powder is distinguished by having an extremely stable bulk density. When poured into a cavity, there is little striation physically or in dielectric properties; the material is extremely stable from point to point
• Most of the powders are usable to temperatures in excess of 500 °F (260 °C)
• ECCOSTOCK® HiK Powder maintains consistent electrical characteristics with respect to frequency in the microwave range. These powders have also been treated to be relatively unaffected by changes in temperature and humidity
• ECCOSTOCK® HiK Powder is of course reusable!

Applications

• ECCOSTOCK® HiK Powders are used to fill complex shapes and cavities for microwave experiments. Devices can be immersed in the dielectric powders to test the effect of special dielectric mediums. For example, an antenna can be immerse in ECCOSTOCK® HiK Powder (K=10) and operated to simulate a re-entry plasma
• Waveguides and cavities can be filled to test the effect of dielectric loading
