Characteristics of Zirconia Ceramics
Whiteness, resistance to corrosion, and strong chemical stability are some of the qualities that distinguish zirconia ceramics. It possesses the finest mechanical qualities of any ceramic material, with the greatest flexural strength and fracture toughness at room temperature, as well as remarkable wear resistance. Although zirconia ceramics are a high-performance material, they have not yet found widespread usage in everyday applications. This is especially true outside of the industrial sectors of machinery, electronics, petroleum, chemicals, aerospace, and textiles. In attempt to face the shortcomings of existing daily needs, this paper presents a novel application of high-performance zirconia ceramics for the creation of new high-grade zirconia daily necessities with high strength, good wear resistance, high toughness, and low breakability.
Application of Zirconia Ceramics in Daily Necessities
In the realm of civil high-tech ceramic product manufacturing, the application of high-performance zirconia ceramics to the production of porcelain for daily use, such as cups, plates, plates, bowls, knives, forks, spoons, and other pieces of tableware and tea sets for daily use, is thought to be a part of the field. Zirconia ceramic powder raw materials used to create everyday essentials are as transparent and clear as zirconium jewels, and they possess the same dazzling brilliance. Consequently, this paper proposes the production procedures of three principal zirconia products.
Production Method of Zirconia Ceramics in Tea or Coffee Set
After the high-density zirconia nano-powder and the polyethylene had been weighed out in accordance with the ratio of 100 parts of zirconia powder to 10 parts of polyethylene, they were placed into an internal mixer to undergo the kneading process. After the ingredients are combined, they are pumped into a mold at 170°C to 200°C and 100MPa of pressure to form the zirconia tea set or the body of the coffee maker, which is then cooled and demolded.
Production Method of Zirconia Ceramics in Tableware
An internal mixer is used to combine the superfine zirconia powder, which is weighed at a ratio of 100 parts zirconia powder to 30 parts paraffin. After the components are combined, the zirconia daily cup, plates, pots, and bowls are produced by injecting the material into a mold at a high temperature (150°C-180°C) and pressure (80MPa), letting it cool and solidify, and then deforming the product.
Production Method of Zirconia Ceramics in Knives, Forks and Spoons
After the ultra-fine zirconia powder and the polypropylene have been weighed out in accordance with the ratio of 100 parts of zirconia powder to 20 parts of polypropylene, the powder and the polypropylene are placed into an internal mixer for the purpose of mixing. The material that has been kneaded is placed in the injection molding machine, and it is then injected into the mold at a certain temperature (150 °C-180 °C) and pressure (90 MPa). After the injection, the mold is allowed to cool and solidify, and then it is released in order to obtain the body of the knife, fork, or spoon.
The aforementioned three varieties of embryos are heated in a furnace so that the green body's organic binder may be extracted without difficulty. Degreasing bodies are sintered in high temperature furnaces. Finally, when the product has been ground and treated, the surface finish can approach the mirror level, which is exceedingly smooth, allowing for the production of high-strength and high-toughness zirconia daily necessities.
Conclusion of Zirconia Ceramics in Daily Necessities
High hardness, good wear resistance, high toughness, a low friction coefficient, and strong corrosion resistance are only some of the benefits of using zirconia ceramics to manufacture daily necessities. As a result, zirconia ceramics offer a wide range of application possibilities and a massive amount of potential market space in the field of daily-use ceramics.
