A sheet forming binder includes a first powder and a second powder having a larger volume average particle size than the first powder. The proportion of the first powder is 10.0% by mass or more relative to the total mass of the first powder and the second powder.

A method of preparing a ceramic fabric for use in a ceramic matrix composite includes transforming a ceramic tow from a first tow geometry to a second tow geometry, thereby reducing a first dimension of the ceramic tow and increasing a second dimension of the ceramic tow orthogonal to the first dimension to produce a flattened tow. The method includes weaving or braiding the flattened ceramic tow to form a ceramic fabric.

A distributor device (1) for distributing a mix (L) in one or more forming supports (S) for manufacturing articles made of composite stone material. The device (1) comprises mix supply means (10) designed to transport the mix (L) along a longitudinal feeding direction (X) towards the forming supports (S). The distribution device (1) further comprises mix lamination means (16) located between the supply means (10) and the supports (S). The invention also relates to a method and a plant for manufacturing articles made of composite stone material which use the aforementioned distributor device (1).

“Green”, ceramic tapes intended as building blocks for making complex, fully ceramic components and devices for electronic-, lab-on-chip-, and sensing applications, the manufacture of which comprises in sequence: I. mixing of a ceramic “green” paste, II. homogenisation of a ceramic “green” paste, III. dimensioning and optionally structuring the ceramic “green” paste, IV. drying of the dimensioned and structured ceramic paste, in which: step iii) is performed in a combination of an extruder and a calender, the extruder being provided with a circular extrusion die, splitting and unfolding the extruded tube to a flat, continuous tape strip, using methylcellulose or derivatives thereof as binder, and, an additional step chosen among cutting and punching the thus dimensioned and optionally structured “green” paste, thereby making thick, “green” tapes. A method for its manufacture is also contemplated.

The present invention relates to a method for manufacturing a low density inorganic powder insulator having a low density molded structure using expanded perlite without a binder and a mold machine for manufacturing the same, and more particularly, to a technology of uniformly dispersing perlite particles having a shape of irregular fragments of glass using expanded perlite to form a framework among synthetic silica to improve molding strength even at a low density, thereby reducing thermal conductivity (conduction and convection blocking) due to a low density and an increase in a specific surface area. Further, the present invention relates to a method for manufacturing a low density inorganic powder insulator having a molded structure using economical expanded perlite having excellent physical properties by compression-molding a clad sheet material using a mold machine having a porous plate and a filter so as to remove pressure and air, which are generated during compression due to the use of the clad sheet material having low specific gravity and a large specific surface area, from a molded product or manufacturing the clad sheet material into a compressed clad sheet using a compression roller, and a mold machine for manufacturing the same.
