摘要： Amorphous precipitated silica is characterized by a standard white area of less than 0.8 percent. The low standard white area is a characteristic of the silica which is indicative of high (i.e., very effective) dispersion when the silica is incorporated into organic rubber compositions which are cured.Cured organic rubber compositions comprising amorphous precipitated silica exhibit low white areas which indicate high dispersion of the silica in the compositions.
摘要翻译： 无定形沉淀二氧化硅的特征在于标准白色面积小于0.8％。 低标准白色区域是二氧化硅的特征，当将二氧化硅掺入固化的有机橡胶组合物中时，其表现出高的（即非常有效的）分散体。 包含无定形沉淀二氧化硅的固化有机橡胶组合物表现出低的白色区域，这表明二氧化硅在组合物中的高分散性。

摘要： Particles comprising particulate amorphous precipitated silica in association with from 5 to 10 percent by weight sodium sulfate and less than 10 percent by weight water, wherein the percentages are based on the weight of the silica, the sodium sulfate, and the water, which particles have a BET surface area of from 100 to 300 m.sup.2 /g, a total intruded volume from 1.8 to 3.6 cm.sup.3 /g, and a DBP oil absorption of from 180 to 320 cm.sup.3 /100 g, may be employed in microporous battery separators to introduce all or a portion of the desired sodium sulfate to the battery electrolyte. Moreover the enhanced amount of sodium sulfate enhances silica characteristics and battery separator production.

摘要： Corrosion inhibiting calcium-containing amorphous precipitated silica is described. The silica is prepared by admixing simultaneously in a reactor aqueous alkali metal silicate, e.g., sodium silicate, acidifying agent, e.g., hydrochloric acid, and a water-soluble source of calcium, e.g., calcium chloride. The product contains from 6 to 9 weight percent calcium (as CaO). The silica product may be incorporated into a coating composition used for corrodible metallic surfaces.

摘要： The present invention is directed to an attrition resistant carrier product such as silica. Further, this invention is directed to the use of a binder to improve the attrition resistance or reduce the friability of a carrier product such as silica. In an embodiment, the median particle size is from 125 to 300 microns. Selection of the binder is such that the presence and/or addition of the binder does not result in substantial modification of the physical properties of the silica. Suitable binders include Group I and Group II silicates, Group I and Group II aluminates, and mixtures thereof, as identified by the Period Table of Elements.
