What Are the Processes for Coloring Zirconia Ceramics?

In recent years, as people’s demand for decorations continues to increase, colored zirconia ceramics have become the new favorite of high-end decorative materials such as bracelets, bracelets, and buttons due to their excellent properties, bright colors, metallic luster, and non-allergic effects.

Zirconia ceramics is widely used for its excellent high-temperature physical and mechanical properties, especially for key components used under harsh conditions. Zirconia ceramics have excellent properties such as high strength, high hardness, good toughness, and corrosion resistance, and are widely used in various fields, such as cutting tools, molds, valve materials, oxygen sensors, solid fuel cells, and decorations.

In recent years, as people’s demand for decorations continues to increase, colored zirconia ceramics have become the new favorite of high-end decorative materials such as bracelets, bracelets, and buttons due to their excellent properties, bright colors, metallic luster, and non-allergic effects.

So, how are colored zirconia ceramics prepared? So what are the ways to color zirconia? The following Mingrui Ceramics will introduce you:

1. First, it is colored by chemical reaction. Mainly in a specific solution, chemical oxidation is used to form the color of the film. However, it needs to be adjusted to ensure the consistency of the color. This method is more common in use.

2. The second is the high-temperature oxidation method. The workpiece must be kept within the scope of the process, and then directly immersed in a specific good molten salt. After the chemical reaction, a layer of uniform thickness will be formed on the surface of The oxide film, and can show a variety of different colors.

3. The last is chemical co-precipitation method. This method is more suitable for use in mass product processing, such as our usual watch straps, many watch straps and watches cases are plated in Titanium gold, so the color is basically golden yellow. The main principle of this method is that the stainless steel workpiece is repeatedly evaporated in a vacuum in a vacuum coating machine. However, because of its relatively high cost, And the investment is relatively large, so it is not suitable for use in the production of small batches of products.
