Төв аймгийн бор-уулын уулын перлитийн дулааны хөөлтийн горим
AbstractThe perlit from Bor-Uul deposit has been studied. We produced expended perlite by a heat expansion principle using a vertical stationary furnace at different conditions. The result showed that the perlite’s expansion significantly depends on the temperature ( 1050-12500С), time of the heating (20-240sec) and the particle size. We have the first time obtained highly expanded perlite with an expansion coefficient equal to 964 be using the vertical furnace at our laboratory.
