Method for thermal insulation of an evacuable container comprising an inner container, an outer container and a cavity disposed between the inner container and the outer container, wherein said method comprises

Method for thermally insulating an evacuable container

A process for producing an ammonia-treated hydrophilic thermal insulation molding which includes treating a thermal insulation molding containing hydrophilic silica with ammonia by introducing the thermal insulation molding into a chamber and supplying gaseous ammonia until a pressure difference &#x394;p of &#x2265;20 mbar is achieved. A process for producing a thermal insulation molding containing hydrophobic silica which includes treating the ammonia-treated hydrophilic thermal insulation molding with an organosilicon compound.

Method for producing a molded heat-insulating element

A method for continuous production of a thermally insulating mixture comprising silica particles and opacifier particles, in which a premixed stream comprising a carrier gas, silica particles and opacifier particles is introduced into a fine impact mill, ground and mixed therein, after which the solid is separated from the gas stream, wherein the fine impact mill is an air-stream mill comprising grinding tracks arranged one above the other on a rotatable shaft.

Method for producing a thermally insulating mixture

Process for hydrophobizing a microporous thermal insulation molding comprising hydrophilic silica, in which the molding is treated with at least one organosilane and in which one or more organosilanes which are gaseous under the reaction conditions are introduced into a chamber containing the microporous thermal insulation molding comprising hydrophilic silica until the pressure difference &#x394;p is &#x2267;20 mbar.

Method for producing hydrophobic, heat-insulating mouldings

A thermal insulation material comprising a precipitated silica having a modified tapped density of less than or equal to 70 g/l.

Thermal insulation material comprising precipitated silica

Formulation comprising hydrophobicized particles of silicon dioxide, mineral oil and one or more emulsifiers, where the hydrophobicized silicon dioxide is a fumed silicon dioxide, possesses a BET surface area of 200 to 300 m/g, has on the surface of the particles O&#x2014;Si&#x2014;(CH)groups, where n is 1 to 3 and where the (CH) units are alike or different, has a carbon content of 1.5% to 5% by weight, based on the hydrophobic silicon dioxide, and is present in the formulation with a fraction of 0.05% to 5% by weight.

Defoamer formulation

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.

Pyrogenic titanium dioxide compressed to slugs

Thermoplastic matrix/compound, comprising thermoplastic polymer and silanised, structurally modified, pyrogenically produced silica.

Thermoplastic compound/matrix

Disclosed are a process for producing a suspension of hydrophobic oxidic particles which has a defined, adjustable viscosity, which comprises suspending low structured hydrophobic oxidic particles in at least one organic suspension agent and then adding from 0.05% to 15% by weight based on the suspension medium of high structured hydrophobic oxidic particles, a suspension of hydrophobic oxidic particles which has a defined, adjustable viscosity and the use thereof for producing soil and water repellent coatings on articles.

Production of suspensions of hydrophobic oxide particles

Aqueous dispersion containing a silicon-aluminum mixed oxide powder, the powder containing 0.1 to 99.9 wt. % AlOand Si&#x2014;O&#x2014;Al-bonds. The dispersion can be produced using dispersing and/or grinding devices which a achieve an energy input of at least 200 KJ/m. The dispersion can be used for the chemical-mechanical polishing of semiconductor substrates.
