The CNTs were grown on the dolomite surface. The combined properties of both materials will improve the dispersion and capability of fillers in polymer composites. In this study, the CNTs-dolomite were produced by using the CVD method (CVD hybrid) and the milling method (physically hybrid) and used as filler in phenolic composite.
In this study, dolomite was proposed as a nanofiller to reinforce the PEVAc. Raw dolomite was physically and chemically modified in order to improve its mix ability and interfacial adhesion between the PEVAc and dolomite. Initially, the size of dolomite was reduced by combining the ball-milling and tip-sonication methods.
Dolomite can be used to make dolomite bricks; when dolomite bricks are used as furnace lining, the method of spraying dolomite gunning materials can significantly increase the life of the furnace. 2. Magnesium smelting industry Dolomite with a raw ore particle size of 30-120mm is an important raw material for the production of metallic magnesium.
