The invention relates to a method of making a sink comprising: cutting out material that will constitute a bottom of the sink; making a hole for a drain in the bottom of the sink; supporting the edges of the bottom of the sink on a flat support and applying a mechanical force on the rim of the hole for the drain in the bottom of the sink; subjecting the bottom of the sink to a gradual and stepwise heating such that the mechanical force applied deforms said surface; cooling a flat slab; placing additional flat slabs around the first slab, on the sides thereof, to constitute the sides of the sink; externally coating the assembly made with a reinforcement comprising resins, glass fiber, mineral fillers, etc.; and bonding the upper part of the assembly made with the countertop where the sink is located.

A process for manufacturing a composite material part includes formation of a fibrous texture from refractory ceramic fibres, placement of the fibrous texture in a mould with interposition of a filtration layer between the fibrous texture and a discharge port, the filtration layer including a partially densified fibrous structure, pressure injection of a slurry containing a powder of refractory ceramic particles into the fibrous texture, drainage by the filtration layer of the slurry solvent having passed through the fibrous texture and retention of the powder of refractory ceramic particles within the texture by the filtration layer to obtain a fibrous preform including the fibrous texture filled with refractory ceramic particles and the filtration layer, heat treatment of the refractory ceramic particles present in the fibrous texture of the preform to form a composite material part including the fibrous texture densified by a refractory ceramic matrix and the filtration layer.

Method of making construction materials intended for use as structural elements, such as structural blocks, used in the construction of buildings and civil engineering structures. In one aspect, the blocks may comprise a body shape configured so as to allow it to interlock with other blocks in the construction of a structure. Methods for manufacturing the blocks and structures comprising such materials and methods for building such structures are also disclosed.

A composite ceramic element and method of firing clay or ceramic elements in a roller kiln, comprising the steps of passing a first ceramic element on rollers through the roller kiln, passing a second ceramic element on rollers through the roller kiln, and mating and securing the first and second ceramic elements together after passing each said ceramic element through the roller kiln.

The present disclosure provides a method of manufacturing a composite sandwich panel having a core formed of a plurality of cells extending vertically between a first skin and a second skin. The method includes creating at least one first strip and a second strip from a temporary material, each strip having at least one cavity having a succession of aligned half-cells, lining the cavity of the first strip with a fibrous ply, assembling the first strip and the second strip by interlocking the cavity of the first strip with the cavity of the second strip and trapping the fibrous ply therebetween, and trimming excess temporary material of the entirety of the strips formed during the preceding assembly step so as to form a new cavity which forms a succession of aligned half-cells.

A honeycomb structure includes honeycomb segments each having a porous partition wall defining a plurality of cells, and includes a porous bonding layer containing a crystalline anisotropic ceramic and disposed so as to bond side surfaces of the honeycomb segments to each other. A ratio of a pore volume (cc/g) of a fine pore defined as a pore in the bonding layer having a pore diameter of 10 m or more and less than 50 m with respect to a pore volume (cc/g) of a coarse pore defined as a pore in the bonding layer having a pore diameter of 50 m or more and 300 m or less is from 2.0 to 3.5, the pore volume of the fine pore is from 0.15 to 0.4 cc/g, and the pore volume of the coarse pore is from 0.05 to 0.25 cc/g.

A container for food liquids, in particular for the storage and/or fermentation of alcoholic beverages, has a body in which a substantial portion of the walls of the container is made of a ceramic material with controlled porosity. The body of the container is shaped as a truncated pyramid, in which each of the faces of the side wall includes a slab of ceramic material with controlled porosity, and in which a support structure made of cementitious material is formed along the external corners of the side wall and in correspondence with the bases of the truncated pyramid. Axial openings are defined in the bases of the container and are adapted to cooperate with suitable closing members.

A ceramic structure and methods for making the ceramic structure are disclosed. Multiple parts may be molded; the parts may be molded from the same or different ceramic materials. The parts may be formed in the same mold and may be adjacent to and/or attached to one another as a result of molding. The parts may be placed in a sintering furnace and sintered simultaneously. Simultaneously sintering the parts forms a unitary structure from the parts.
