The reporter learned from the Baotou Rare Earth R & D Center of the Chinese Academy of Sciences that China ’s first pilot production line of rare earth glaze ceramics produced finished rare earth glaze ceramics, setting a precedent for the preparation of traditional ceramic products with new materials in China.
It is understood that the R & D project of rare earth glaze ceramics was officially established in 2017. After two years of technical research, the pilot production has now officially started. Project leader Liang Lei said, "The core technology of the project is to use the unique electronic structure layer of rare earth elements for glaze blooming. After high temperature firing from 1200 to 1300, the modification and modification of other substances in the glaze are realized. Hair color effect, forming glaze effects such as snowflakes, rainbows, cherry blossoms, starry sky, ice cracks. "
Chi Jianyi, director of the Baotou Rare Earth R & D Center of the Chinese Academy of Sciences, told reporters that the development of this new technology was inspired by Baotou ’s rich rare earth resources and environmentally friendly ceramic manufacturing concepts: "In general, the colorful ceramic products on the market will contain a large amount of lead and cadmium Such as heavy metal elements, some products even lead content of more than 30%, although fired into porcelain does not have a direct impact on the human body, but the storage of acidic items will cause the heavy metals to dissolve out and pose a health hazard. "
The reporter saw on the production line that as long as the operator made a few adjustments to the rare earth raw materials and the addition ratio, the color glaze ceramics would have a variety of effects on colors and patterns. "More importantly, rare earth glaze ceramics are typical environmentally friendly products. They do not contain any harmful substances and radiation. On the contrary, they also have bactericidal and antibacterial functions." Liang Lei said.
After the rare earth glaze ceramic products are produced, they are sent to a number of domestic testing institutions such as Jiangxi and Guangdong for testing. The test report shows that the ceramic sample submitted for inspection is toxic and harmful and the test result is "NO". Chi Jianyi told reporters: "This means that the rare earth glaze ceramics we produce can be taken orally to hold rice and water. In addition, we have obtained data that rare earth glaze ceramics are rare earth glaze ceramics with antibacterial functions. Staphylococcus aureus The antibacterial rate is greater than 99.99%, and the antibacterial rate of E. coli is 99.9%. "
As of press time, this rare earth glaze ceramic has the advantages of wear resistance, corrosion resistance, radiation-free, lead-free cadmium dissolution, and antibacterial function. It has already applied for 4 national patents.
