[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In this invention, during the preparation of ceramic parts, the addition of a mixture of base materials and auxiliary materials in the filler formulation allows soybean fiber protein and hydroxymethyl cellulose to strengthen the bonding during the initial mixing process, making the bonding between the materials more stable. During high-temperature sintering, soybean fiber protein and hydroxymethyl cellulose undergo thermal decomposition, which helps to solidify the bonding of the materials during the initial heating process, reducing the shrinkage rate during sintering and improving the overall structural stability. Hexagonal boron nitride powder plays a good role in energy conduction support in the material system, and the addition of nano-silica fills the pores, making the structure of the ceramic parts more compact. At the same time, the composite phase generated by the reaction of boric acid and dicyandiamide can reduce the sintering temperature, avoid excessive grain coarsening, and further ensure the structural strength of the ceramic parts.

[0024] 2. In this invention, by adding powder, the porous structure of diatomaceous earth can adsorb other component materials, ensuring that each material is evenly distributed and reducing stress concentration caused by particle agglomeration. Agar can dissolve during the preparation of powder to form a hydrogel network, temporarily fixing the particle position and improving the strength of the blank. Through the plasma treatment during the filler preparation process, an etched structure can be generated on the material surface, improving the interfacial bonding strength of the material and further ensuring the structural strength of the ceramic part.

[0077] Performance testing: The ceramic parts prepared in Examples 1, 2, 3, 1, 2, 3, and 4 were subjected to performance tests, and the test data are recorded in the table below:

[0078]

[0079] In the performance test, the test standard in GB / T3810.4 was adopted to test the compressive strength of the ceramic parts prepared in Example 1, Example 2, Example 3, Comparative Example 1, Comparative Example 2, Comparative Example 3 and Comparative Example 4.

[0080] The flexural strength of ceramic parts prepared in Examples 1, 2, 3, 1, 2, 3 and 4 was tested using the test standards in GB / T3810.3-2016.

[0081] It is evident that the compressive strength and flexural strength of the ceramic parts prepared in Comparative Examples 1, 2, 3, and 4 are all lower than those in Examples 1, 2, and 3. This indicates that in the preparation of ceramic parts, the addition of mixed materials of base and auxiliary materials in the filler formulation, such as soybean fiber protein and hydroxymethyl cellulose, can strengthen the bonding during the initial mixing process, making the bonding between the materials more stable. During the high-temperature sintering process, soybean fiber protein and hydroxymethyl cellulose will undergo thermal decomposition, while during the initial heating process, the materials can be firmly bonded, reducing the shrinkage rate during sintering and improving the overall structural stability. Hexagonal boron nitride powder can play a good energy conduction support role in the material system, and the addition of nano-silica can fill the pores, making the structure of the ceramic parts more compact. At the same time, the composite phase generated by the reaction of boric acid and dicyandiamide can reduce the sintering temperature, avoid excessive grain coarsening, and further ensure the structural strength of the ceramic parts.

[0082] By adding powder, the porous structure of diatomaceous earth can adsorb other component materials, ensuring uniform distribution of each material and reducing stress concentration caused by particle agglomeration. Agar can dissolve during the preparation of powder to form a hydrogel network, temporarily fixing the particle position and improving the strength of the blank. Through ionization treatment during the filler preparation process, etched structures can be generated on the material surface, improving the interfacial bonding strength of the material and further ensuring the structural strength of the ceramic parts.

[0083] By comparing and analyzing the relevant data in the table, it can be seen that the ceramic parts prepared by this invention not only have good compressive strength but also excellent flexural strength. This indicates that the ceramic parts provided by this invention have a broader market prospect and are more suitable for widespread application.
