Is ceramic disinfection tableware poisonous when heated?

Nowadays, the common material of disinfection tableware is Ceramic. Everyone knows that this kind of tableware is recycled and will undergo strict cleaning and disinfection after use, however, some people will also say that there is usually a process of high-temperature sterilization when disinfecting, so considering the material, do you think that high-temperature heating will release toxic substances from ceramic tableware? Next, let's talk about whether it will be poisonous. Ceramic tableware is mainly to consider whether lead and cadmium exceed the standard. If you use such tableware exceeding the standard for a long time, the lead and cadmium in it will enter the body with food. Lead can exist in blood for a long time, causing spasm of vascular smooth muscle, ischemia of liver, kidney, brain and other important organs, damage cells, and affect normal metabolism of nerve cells, it also has a bad effect on the intellectual development of children and adolescents. Kidney is the main target organ of cadmium damage and accumulates in bones, which can lead to the decline of human immunity, joint deformation and pain, but the disinfection tableware with qualified quality is strictly controlled, don't worry when you use it. Generally speaking, lead and mercury will exceed the standard for ceramic disinfection tableware with low price. The better price is that it takes a long time in the process of firing ceramics, which is relatively safe. Ceramics have no plastic deformation at normal temperature, and their compressive strength is large, while their tensile, bending and impact strengths are small, showing easy brittle fracture. According to the ratio of materials, the theoretical strength of ceramics is very high, but its actual strength is only about 1% of the theoretical strength. The reason is that the sintering conditions and processes of ceramics are different, and their multiphase structures are also different. In addition, when the ceramic disinfection tableware is heated to the critical temperature of porcelain, creep can occur, and its creep is more obvious at high temperature. That is to say, during the sintering process, the creep of the porcelain often pulls the metal to deform, especially the repeated sintering of the multi-unit porcelain crown Bridge, and the possibility of deformation is greater. Through the introduction, we all know that the use of unqualified ceramic products for tableware is easy to affect our health due to high temperature, so the use of unqualified ceramic disinfection tableware is very harmful, in order to avoid using this kind of unqualified tableware, it is recommended that you go to a regular place where the quality of the goods is guaranteed to buy tableware.
