A method and apparatus for detecting aluminum carbide content includes a right-angle tube I connected to a round-bottom flask via a rubber stopper I at its inlet. One end of the rubber tube I is connected to one port of a three-way valve, and the other two ports of the three-way valve are connected to rubber tubes II and III, respectively. The other end of the rubber tube II is connected to the gas inlet of a gas chromatograph. The other end of the rubber tube III is connected to the inlet of the right-angle tube II. The outlet of the right-angle tube II, a thermometer, and the inlet of the right-angle tube III are all embedded in the rubber stopper II and installed at the mouth of a specially designed measuring cylinder. The outlet of the right-angle tube III is connected to the inlet of the right-angle tube IV via a rubber tube IV. The outlet of the right-angle tube IV, along with a glass tube, is embedded in the rubber stopper III and installed at the mouth of a conical flask. By measuring the gas volume and composition sequentially through the three-way valve, the aluminum carbide content in the sample is determined using a function model. This allows for direct observation of changes during the detection process, effectively reducing operational errors and improving the accuracy of the detection results.

The application belongs to the technical field of energy storage, and discloses a lithium-aluminum carbide-zinc composite lithium metal negative electrode and a preparation method and application thereof. A multi-phase alloy phase (Li single element, Al single element, LiZn alloy, Li3Al2 alloy and Li2C2) is formed by smelting of metal lithium, aluminum carbide and zinc single element. The lithium-aluminum carbide-zinc composite lithium metal negative electrode enhances the tensile strength and controls lithium stripping and deposition due to the presence of the LiZn alloy, the Li3Al2 alloy and the Al single element. The Li2C2 carbon-containing compound enhances the mechanical toughness of the composite lithium metal negative electrode. Compared with the existing pure lithium metal negative electrode, the lithium-aluminum carbide-zinc composite lithium metal negative electrode greatly improves the tensile strength, essentially improves the mechanical performance, and this characteristic inhibits the formation of lithium dendrites in the deep stripping and deposition process of lithium.

This method uses carbon-containing refractories, including magnesia, as a starting material to produce recycled magnesia refractory raw materials in which aluminum carbide is removed while suppressing the formation of brucite, and graphite is removed while reducing energy consumption compared to conventional technologies. [Solution] A method for producing recycled magnesia refractory raw material, comprising a heating and pressurizing step of heating and pressurizing a carbon-containing refractory material containing magnesia in a steam atmosphere to obtain a treated material, and a graphite removal step of removing at least graphite particles from the treated material.
