Embodiment Construction

[0014] The present invention proposes a silver-white zirconia ceramic product, including bowls, plates, basins, pots, vases, etc., the shape may not be limited to a specific form, but its material is made of zirconia (ZrO2) base material. There is a layer of zirconium carbide (ZrC) film.

[0015] The zirconium carbide film is a silver-white, high-hardness material that produces a good appearance (equivalent to stainless steel) after polishing.

[0016] The zirconium carbide film uses the existing carbon atmosphere vacuum furnace generally used to produce tungsten steel products. The white zirconia product is heated to 1500 ℃ ~ 1600 ℃ in the furnace, and after 2 to 5 hours of heat preservation, the surface of the ZrO2 product Form a layer of high hardness anti-scratch film, that is, the zirconium carbide film.

[0017] The chemical reaction formula is as follows: ZrO2+C→ZrC+CO2

[0018] The present invention also provides a method for manufacturing the above-mentioned silver-...

Abstract

The present invention is one kind of silvery white zirconia ceramic product and its making process. The silvery white zirconia ceramic product has zirconia base and one layer of zirconium carbide film, which is formed through heating white zirconia product at 1500-1600 deg.c inside carbon atmosphere in a vacuum furnace and maintaining for 2-5 hr. The silvery white zirconia ceramic product is environment friendly, radiation-proof, low in production cost and simple in production process.

Description

technical field [0001] The invention relates to a silver-white zirconia ceramic product and a manufacturing method thereof, in particular to a silver-white zirconia ceramic product and a manufacturing method thereof that are environment-friendly, radiation-proof, human body is not prone to allergies, production cost is not wasted, and production process is simple. Background technique [0002] The traditional zirconia ZrO2 itself is a white powder, and there are various color and white coloring materials on the market, but there is no silvery white in the final products. The traditional manufacturing process is: mixing → glue mixing → degumming → sintering → polishing (white zirconia at a temperature of 1400 ° C ~ 1580 ° C), which cannot be made into silver white. Contents of the invention [0003] The technical problem to be solved by the present invention is that traditional zirconia ceramic products cannot produce silver-white products. [0004] In order to solve the a...
