Method of compacting a fumed metal oxide-containing composition

Abstract: A method of compacting a fumed metal oxide-containing composition is disclosed. In the method of the present invention, the fumed metal oxide-containing composition is treated with vapor comprising water such that the vapor is adsorbed into the fumed metal oxide so as to produce a vapor-treated fumed metal oxide-containing composition. Pressure is applied to the vapor-treated fumed metal oxide-containing composition to reduce the volume of the metal oxide-containing composition so as to produce a compacted metal oxide-containing composition, which is characterized by a volume springback that is less than the volume springback of the same compacted metal oxide-containing composition prepared in the absence of said vapor treatment.

Method for the preparation of organically modified aerogels

Abstract: The invention relates to a process for producing aerogels with permanently hydrophobic surface groups, in which a) silicate lyogel is provided, b) the gel provided in step a) is washed with an organic solvent, c) the gel obtained in step b) is surface silylated and d) the surface-silylated gel obtained in step c) is dried, where the organic solvent used in step b) is a diether of formula (I) R 1 --O--(CH 2 ) n --O--R 2 in which R 1 and R 2 are mutually independently the same or different alkyl groups with 1 to 4 C atoms and n is a natural number in the range from 1 to 5.

Alloys resistant to localized corrosion, hydrogen sulfide stress cracking and stress corrosion cracking

Abstract: An alloy and a metal product characterized by resistance to localized corrosion, hydrogen sulfide stress cracking (hydrogen embrittlement) and stress corrosion cracking at temperatures up to about 200° C. consisting essentially of nickel 40-65%, cobalt 0-5%, chromium 10-20%, molybdenum 12-18%, iron 10-20%, tungsten up to 5%, carbon 0-0.1% manganese up to 3%, vanadium up to 1% and silicon up to 0.2%. The alloy resistance is maintained when it is cold worked over 20%.

Method of producing high surface area low metal impurity tantalum powder

Abstract: A process for producing a high purity tantalum powder wherein a small quantity of an active ingredient, having a higher thermodynamic potential and chemical activity than the metal surfaces of the reactor vessel, is added to the reactor before the reactor is heated to reaction temperatures.
