A method for forming a hole in a ceramic matrix composite (CMC) component may be provided. A sacrificial fiber having an environmental barrier coating on an outer surface thereof may be inserted into a porous ceramic preform that includes ceramic fibers. The ceramic preform may be formed into a ceramic matrix composite body. The sacrificial fiber may be removed from the ceramic matrix composite body, the environmental barrier coating of the sacrificial fiber defining an opening in the ceramic matrix composite body. A ceramic matrix composite component may be provided. The ceramic matrix composite component may include an environmental barrier coating of a sacrificial fiber, where the environmental barrier coating forms a lining of a hole passing partly or entirely through a thickness of the ceramic matrix composite body.

The present invention relates to a system and method for the production of gypsum board using starch pellets. In accordance with the present disclosure, the starch necessary for board formation is provided in the form of starch pellets. These pellets are mixed with a gypsum slurry in a mixer. The pellets are initially insoluble and do not dissolve. However, during subsequent drying stages, the pellets become soluble and dissolve into the gypsum phase. This both provides the desired starch component and also results in the formation of voids within the set gypsum.

The invention relates to a method for economically producing a composite powder made of carbon and electrochemical active material. According to the invention, a melt made of a meltable carbon precursor substance having nanoparticles made of an active material distributed in the melt is provided, and said melt is divided into the composite powder, in which nanoparticles made of the active material are embedded in a matrix made of the carbon precursor substance. A porous composite material produced using the composite powder is used to produce an electrode for a secondary battery, in particular for use as an anode material. The production of the composite material comprises the following steps: providing template particles made of inorganic template material, producing a powder mixture of the composite powder and the template particles, heating the powder mixture and softening the composite powder in such a way that the composite powder penetrates the pores and is carbonated, and removing the template material to form the porous electrochemical composite material.
