A method for making a composite material and composite material

2025

Abstract

Herein described is a method for making a composite material, comprising the steps of (a) swelling a blank hydrogel or a blank organogel using an inorganic precursor mixture to form an inorganic precursor-containing solvent-containing gel, wherein the inorganic precursor mixture comprises a solvent and one or more inorganic precursors, and (b) converting the inorganic precursor into ceramic or metal within the solvent-containing gel by introduction of reagents and/or stimuli to obtain a composite material. Optionally, the composite material can be converted into an inorganic material with an additional step (c) comprising thermally treating the composite material. Also described are the resultant composite material and the optional resultant inorganic material.

Hydrogen fluoride

Hydrogen fluoride (fluorane) is an inorganic compound with chemical formula . It is a very poisonous, colorless gas or liquid that dissolves in water to yield an aqueous solution termed hydrofluoric acid. It is the principal industrial source of fluorine, often in the form of hydrofluoric acid, and is an important feedstock in the preparation of many important compounds including pharmaceuticals and polymers, e.g. polytetrafluoroethylene (PTFE). HF is also widely used in the petrochemical industry as a component of superacids.

Inorganic chemistry

Inorganic chemistry deals with synthesis and behavior of inorganic and organometallic compounds. This field covers chemical compounds that are not carbon-based, which are the subjects of organic chemistry. The distinction between the two disciplines is far from absolute, as there is much overlap in the subdiscipline of organometallic chemistry. It has applications in every aspect of the chemical industry, including catalysis, materials science, pigments, surfactants, coatings, medications, fuels, and agriculture.

Composite material

A composite material (also called a composition material or shortened to composite, which is the common name) is a material which is produced from two or more constituent materials. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. Within the finished structure, the individual elements remain separate and distinct, distinguishing composites from mixtures and solid solutions.
