摘要:
Pyrogenic titanium dioxide is compressed to slugs by preliminarily deaerating it, compressing it to slugs, and crushing the slugs and optionally classifying them. The slugs are characterized by a tamped density (to DIN EN ISO 787-11) of 500 to 1200 g/l.

摘要:
Process for preparing an aluminum oxide powder which is present in the form of aggregated primary particles and comprises at least 85% by weight of alpha-aluminum oxide, in which an aluminum oxide powder which a) is present in the form of aggregated primary particles, b) is selected from the group consisting of gamma-aluminum oxide, theta-aluminum oxide, delta-aluminum oxide and/or X-ray amorphous aluminum oxide, and c) has a tamped density of at least 250 g/l, is subject to a heat treatment at 13000 C or more and subsequently milled. Aluminum oxide powder which can be obtained by this process. Aluminum oxide powder in the form of aggregated primary particles having a BET surface area of from 3 to 30 m2/g, in which the proportion of alpha-aluminum oxide is at least 85% by weight and the ratio dgo/dio of the weight distribution of the primary particles is at least 2.8. Use as constituent of fluorescent tubes.

Flakes comprising pyrogenically prepared silicon dioxide were rendered water repellent after compacting. They can be used in natural rubber and synthetic rubber production.
摘要:
Pyrogenically prepared silicon dioxide is compacted to give crusts, in that it is subject to preliminary de-aeration, and is compacted to give crusts, and the crusts are broken and, if appropriate, classified. The tamped bulk density (to DIN EN ISO 787-11) of the silicon dioxide compacted to give crusts is from 185 to 700 g/l. It can be used as filler in rubber mixtures.
