Natural and Artificial Micro-silica as Fillers for Vacuum Insulation Panels
The complex studies of the structure and properties of some natural and artificial micro-silica with the purpose to find a suitable material for fillers of vacuum insulation panels havebeen conducted. The parameters of the non-homogeneities of nano-meter scale of amorphous silicon dioxide particles are determined. Thecomparative analysis of studied dispersionswith a powder-filler of foreign production is made. Experimental samples of the vacuum insulation panels were made, their efficient heat conductivitywas measured. Recommendationsfor the production of powder-fillers from local mineral raw materials are given.
