A method of forming a ceramic product, the method comprising producing a ceramic forming mixture in the form of a slurry, causing the slurry to form, extruding the formed slurry to produce a plurality of lengths of extruding material each with a diameter of less than 10 mm, firing the extruded material so as to partially sinter the extruded material, forming the partially sintered extruded material into a required shape for a product, and subsequently firing the shaped partially sintered extruded material to form the ceramic product.

Silicon particles for active materials and electro-chemical cells are provided. The active materials comprising silicon particles described herein can be utilized as an electrode material for a battery. In certain embodiments, the composite material includes greater than 0% and less than about 90% by weight of silicon particles. The silicon particles have an average particle size between about 0.1 m and about 30 m and a surface including nanometer-sized features. The composite material also includes greater than 0% and less than about 90% by weight of one or more types of carbon phases. At least one of the one or more types of carbon phases is a substantially continuous phase.

A method of processing a ceramic matrix composite (CMC) component includes extracting silicon from a surface region of the CMC component such that free silicon is present in the surface region at a reduced amount of about 5 vol. % or less. The extraction comprises contacting the surface region with a wicking medium comprising an element reactive with silicon. The extraction is carried out at an elevated temperature prior to assembling the CMC component with a metal component.

A core component is made of a sintered body of an inorganic powder, in which the core component includes a columnar winding portion and a flange portion integrally formed with the columnar winding portion at both axial ends of the winding portion, and a gap C, represented by the following Formula, between adjacent voids in the surface layer portion of the columnar winding portion, is 6 to 12 m.

Formula: C=LR

where, L is the average value of the distance between the centers of gravity between adjacent voids, and R is the average value of equivalent circle diameters of the voids.

In a method for obtaining a compacted material, a) a set of particles of raw materials is mixed with 1-50% by weight of a hydraulic binder to form a dry composition, the percentage being relative to the total weight of the dry composition, the particle size distribution of the raw material particles being characterised by a first reference diameter 50 millimetres and a second reference diameter 0.08 micrometres, b) the dry composition is mixed with 1-35% by weight of water to form a mixed composition, the percentage relative to the total weight of the dry composition, c) the mixed composition is vibrated 0.3 millimetres at 20-80 Hertz, while a compressive stress is applied, the value of the applied compressive stress being at least 2 MegaPascal. Also disclosed is a method for obtaining a multilayer compacted material and to the materials obtained according to the methods.

A format compensator for a pressing device, comprising a compensating element (7) of a given thickness (S), structured so as to be interposed between the lower punch and the upper punch (10, 11) of a pressing device so as to be arranged in contact with the punches (10, 11) during pressing.

The proposed solution solves a problem of designing a machine for producing molded composite parts that are homogeneously structured and the problem of finding a method for producing composite for implants. The essence of the design of the machine consists in that it has a portioning assembly, whereby above a mold form unit (14) there is a guiding unit (11) located opposite a dosing unit (6) and above the aforementioned guiding unit (11) there is a pressing assembly (20) slidingly mounted on a vertical frame (19) and which is equipped with at least one piston rod (25) with a rammer (27) at its end.

A preliminary molding is being performed by thoroughly filling a preform trough and then the matter is being pushed out of the preform trough in portions and then each portion is rammed separately until consistency containing less than 15% air is achieved.
