Mingrui Ceramics will introduce the preparation method of black zirconia precision ceramics.
Step 1. Use zirconia powder as the base material, add one or more raw materials of cobalt ferrite, cobalt oxide, and cobalt aluminate as a colorant, add a polyvinyl alcohol aqueous solution as a binder, and add a black zirconia precision ceramic plate. .
Step 2: Put the mixture of ceramic raw materials in step 1 into a ball-milling bottle and ball-mill until it is evenly mixed, pour out the suspension in the ball-milling bottle, dry to remove liquid moisture, and obtain ceramic powder.
Step 3: Press the ceramic powder obtained in Step 2 into a desired ceramic body by dry pressing or isostatic pressing.
Step 4. Put the ceramic body obtained in Step 3 into a high-temperature sintering furnace after slow debinding and sintering into a product. The invention has a colorant that can exist stably at a high temperature of 1500° C., and the colorant can color the zirconia into a black zirconia fine ceramics preparation method under the premise of ensuring that the zirconia is fully sintered densely.
Zirconia precision ceramics have high mechanical strength, high insulation resistance, high hardness, wear resistance, corrosion resistance and high temperature resistance - a series of excellent properties, which are widely used in various industries such as ceramics, textiles, petroleum, chemical, construction and electronics. Oxide ceramics are new ceramic materials that are widely used and have a large production and sales volume.
