Abstract

The invention discloses a high-wave-transmission green zirconia ceramic, which is prepared from the following raw materials: yttrium-stabilized zirconia and a green colorant. The dosage of yttrium oxide in the yttrium-stabilized zirconium oxide is 3.5-5.5 mol% of that of zirconium oxide. The green colorant is composed of aluminum oxide, zinc oxide, nickel oxide, iron oxide, titanium oxide, cobaltoxide and manganese oxide according to the molar ratio of (16-60): (1.5-10): (0.8-25): (0.2-17): (0.05-10): (0.04-4): (0.04-0.4), and the addition amount of the green colorant is 2.0-7.0 wt% of the yttrium-stabilized zirconia. The ceramic is of a sandwich gradient composite structure, an upper layer and a lower layer are compact layers, and a middle layer is a porous layer. In addition, the invention also discloses a preparation method of the high-wave-transmission green zirconia ceramic and a prepared product. According to the invention, the adopted raw materials are green, environment-friendly and rich and easily available in source, and by optimizing the formula composition and structural design of the raw materials, the formed high-wave-transmission green zirconium oxide ceramic is excellent in dielectric property and excellent in color generation, and can well meet the market requirements and the strict use requirements in practical application.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to a high-transmittance green zirconia ceramic used in consumer electronic products, a preparation method thereof, and a prepared product. Background technique [0002] Zirconia ceramics have excellent properties such as high strength, high hardness, and corrosion resistance. In addition, they also have the advantages of low thermal conductivity, low thermal expansion coefficient, low friction coefficient, and high chemical stability. Therefore, zirconia ceramics are widely used and have been widely used in refractory materials, high-temperature structural materials, electronic materials, tableware materials, molds, solid fuel cells, oxygen sensors and other fields. [0003] In recent years, due to its excellent performance, good biocompatibility, and no stimulation to the human body, zirconia has also continued to shine in the application of consumer goods, such as bracel...
