Abstract
Fine particles of a highly porous, low density material in which the pore chambers have been at least partially evacuated and refilled with a gas having a low thermal conductivity, and the obtained particles are encapsulated with a protective, durable coating. The particles are particularly useful as durable thermal insulating material.
Claims20
Particles of a material having a porosity of at least 80% and pore chambers filled with a gas having a low thermal conductivity, wherein the particles are encapsulated in a protective, durable coating having a thickness of at most 0.5 mm.
