The present invention relates to a manufacturing method of construction aggregates using incineration ash, in which aggregates for construction, such as gravel or sand are manufactured using incineration ashes produced during the incineration process of household waste, food waste, sewage waste, construction and industrial waste, etc. while realizing eco-friendly manufacturing environments, reducing costs through successive steps and reducing and discharging harmful gases produced during firing.

A method for forming a complex shape three-dimensional ceramic article by printing a first layer of a first material having a first fraction of first ceramic particles and a first fraction of a first polymeric ceramic precursor. A second layer is printed such that it is at least partially disposed on the first layer of a second material having a second fraction of second ceramic particles and a second fraction of a second polymeric ceramic precursor. A composite of the first layer and the second layer is heated at a temperature sufficient to decompose the first and second polymeric ceramic precursors and sinter the article. During the sintering process, the first and second layers with different fractions of ceramic particles undergo different degrees of shrinkage, resulting in a tuneable mismatch of the bilayer structure and accurately achieving a targeted geometry.

A method for injecting a loaded suspension into a fibrous texture having a three-dimensional or multilayer weaving includes the injection of a suspension containing a powder of solid particles into the volume of the fibrous texture. The injection of the loaded suspension is carried out by at least one hollow needle in communication with a loaded suspension supply device, each needle being movable in at least one direction extending between a first face and a second opposite face of the fibrous texture so as to inject the loaded suspension at one or more determined depths in the fibrous texture.

A method for machining by laser ablation or by micro-milling a raised and/or hollow structure on an impression of an injection mould. A method for manufacturing a ceramic or cermet item by injection using the injection mould to produce an item, and in particular a watch bezel, decorated directly during the injection.

This document describes systems and processes for forming synthetic molded slabs, which may be suitable for use in living or working spaces (e.g., along a countertop, table, floor, or the like).

What is shown and described is a concrete element including a core concrete layer and a face concrete layer, the face concrete layer being obtained by compacting and hardening a mixture containing a latent hydraulic binder and/or a pozzolanic binder, water, a granular material and an alkaline hardener, with the granular material having, at a screen hole width of 2 mm, a through fraction from 35.5 wt. % to 99.5 wt. % and, at a screen hole width of 0.25 mm, a through fraction from 2.5 wt. % to 33.5 wt. %, each based on the total weight of the granular material.

Provided herein are processes for transferring high quality large-area graphene layers (e.g., single-layer graphene) to a flexible substrate based on preferential adhesion of certain thin metallic films to graphene followed by lamination of the metallized graphene layers to a flexible target substrate in a process that is compatible with roll-to-roll manufacturing, providing an environmentally benign and scalable process of transferring graphene to flexible substrates.

A ceramic pressure sensor is described which is produced using an alternative production method and has a ceramic base body, a ceramic measuring membrane which is disposed on the base body and is to be charged with a pressure to be measured, and a pressure measuring chamber enclosed in the base body below the measuring membrane. A method to produce the pressure sensor by means of which, in particular, more complex shapes of the measuring membrane and/or the base body are producible with minimal pores wherein the base body and/or the measuring membrane have layers applied on each other in a 3-D printing method and produced by the selective laser melting of nanopowder layers.

The present invention provides a sealing member which includes a substrate including silicon carbide; and a plurality of cylindrical or polygonal columnar graphites dispersed in the substrate, and a method for manufacturing the same.

A method for producing microencapsulated fuel pebble fuel more rapidly and with a matrix that engenders added safety attributes. The method includes coating fuel particles with ceramic powder; placing the coated fuel particles in a first die; applying a first current and a first pressure to the first die so as to form a fuel pebble by direct current sintering. The method may further include removing the fuel pebble from the first die and placing the fuel pebble within a bed of non-fueled matrix ceramic in a second die; and applying a second current and a second pressure to the second die so as to form a composite fuel pebble.
