Abstract

The invention relates to a ceramic preparation method, a ceramic and a basalt wire-drawing bushing. The ceramic preparation method includes the steps: respectively preparing lanthanum chromite, graphene and additive powder; preparing a green ceramic plate from the prepared lanthanum chromite and additive powder; compounding a graphene layer on the prepared green ceramic plate; hot pressing and sintering the green ceramic plate and the graphene layer. The porosity of the ceramic prepared by the ceramic preparation method can be controlled within 20%. The ceramic is uniform in texture and not easy to crack, and has good high temperature resistance and conductivity. In addition, the ceramic has high strength and excellent bending resistance and break resistance and can bear a certain load. Therefore, the ceramic preparation method can be used for preparing special process equipment such as a bottom plate of the basalt wire-drawing bushing for replacing a traditional bottom plate made of platinum rhodium, and production cost is greatly reduced while good service performances are ensured.

Description

technical field [0001] The invention relates to the technical field of material manufacturing, and more specifically, relates to a preparation method of ceramics, ceramics and basalt wire drawing bushings. Background technique [0002] In the field of advanced manufacturing technology, such as the field of basalt fiber manufacturing technology, there are often extremely high requirements on the high temperature resistance, electrical conductivity and strength of production equipment. [0003] In the process of drawing wire from the basalt high-temperature solution, the wire drawing bushing needs to be operated at a very high temperature, even as high as 1200-1300 ° C, which requires the wire drawing bushing to have good high temperature resistance during the working process . [0004] On the other hand, due to the high melting temperature, high viscosity and easy crystallization of basalt, the drawing temperature is difficult to control, and the bottom plate of the drawing ...
