Summary: | The invention discloses a welding flux containing V and Te as well as a preparation method and application thereof, relates to the technical field of welding fluxes, and solves the problem that a low-temperature lead-free welding flux is too high in expansion coefficient. The invention discloses a high-temperature-resistant ceramic which is prepared from the following components in parts by mass: 1.5 to 2.98 parts of MgO, 9.5 to 27.5 parts of Al2O3, 9.46 to 30.58 parts of SiO2, 1.2 to 2.8 parts of P2O5, 1.9 to 8.1 parts of Li2O, 11.8 to 31.8 parts of V2O5, 1.3 to 3.28 parts of ZnO and 18.9 to 43.4 parts of TeO2. The preparation method comprises the following steps: weighing the components in proportion, pouring into a mixing barrel, and uniformly stirring; putting the mixture into a dry pot, putting the dry pot into a muffle furnace, and carrying out heating treatment; and the product is smashed and ground to obtain primary solder powder, and then the primary solder powder is screened through a screen to obta |
