Abstract: Pptd. silica contg. B has the following properties: BET surface are (DIN 66 131) 140 plus-or-minus 60 mg2/g.; loss on drying (DIN 55 921) 2.0-4.0 wt. %; less on calcination (DIN 55 921) 2.5 plus-or-minus 1.0 wt. %; pH (DIN 53 200) 4.0-7.0; conductivity in 4% aq. dispersion 300 muS; tamped density (DIN 53 194) 110 plus-or-minus 4.0 g./l.; B2O3 content 4-20 wt. %; SO3 content 0.25-wt. % and Na2O content 0.25 wt. % after drying 2 hrs. at 105 degrees C. This material is claimed for use as filler in diorganopolysiloxane-based compsns. which cure to elastomers. This filler, like B2O3 and its cpds., effects the condens. of silanol gps. at elevated temp., giving bounding putty. It avoids the danger of higher B cpds., which can be toxic in vapour form, evaporating or diffusing from the mixt.

Wt.-% 0.3-50 -Sieve residue according -to Mocker 45 mu m -(DIN 53 580) Wt.-% 0.2 - They are prepared by adding a cerium (IV) salt solution to the original precipitated suspension of a precipitated silica. The compositions produced with the cerium containing precipitated silica hardenable elastomers based on diorganopolysiloxanes exhibit excellent heat stability. Additionally, the cerium containing precipitated silica acts as a fire retardant agent.
