— Silicon is the eighth most abundant element in the universe. Silicon dioxide (or silica) is present in over 90% of the minerals that make up the earth's crust. Man's use of silica-based minerals dates back to the very origins of recorded human history. Ancient man used flint to strike sparks for the fires they needed to stay warm, while today modern …

Precipitated silica, owing to its high coverage of silanol groups, interacts less strongly than carbon black with hydrocarbon rubbers, and forms stronger interaggregate bonds (network) and (Wolff and Wang 1992). This leads to higher hysteresis which does not set in until higher strain amplitudes. At high elongations silica compounds have low ...
