A kind of high-strength pink zirconia ceramic powder and its preparation method and application

Abstract

The invention discloses a high-strength pink zirconia ceramic powder, the chemical composition of which is zirconia and an added oxide; the content of the added oxide is 0.5-4.0 mol% of erbium oxide, yttrium oxide 0.5-4.0 mol%, magnesium oxide 0.1-0.3 mol%, aluminum oxide 0.1-0.3 mol%. In addition, the preparation method and application of the above-mentioned high-strength pink zirconia ceramic powder are also disclosed. The powder raw material with stable composition and excellent performance obtained by optimizing the composition of the formula in the present invention is conducive to obtaining pink aesthetic ceramic products with high strength, good toughness, good color development, high moisturization and few surface defects, so that it can be well It can fully meet the stringent processing requirements in practical applications, and is conducive to broadening its application fields, with significant economic benefits and broad application prospects.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to a pink zirconia ceramic powder for consumer electronic products and a preparation method and application thereof. 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, daily kitchen 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 bracelets, watch chains,...

AI Technical Summary

Problems solved by technology

However, most of the existing consumer electronic products are black and white zirconia ceramics, lacking more beautiful color products, which cannot well meet the needs of consumers

For this reason, colored zirconia ceramics have also been researched and developed in recent years, but there are still common defects such as dull hair color, poor appearance, and low mechanical properties, which are difficult to meet the actual needs of manufacturing, processing, markets, and applications.
