Can the crockery be placed in the freezer?
Although ceramic tableware can be used in refrigerated freezers, this can lead to shorter service life and easy cracking, preferably with stainless steel cutlery or plastic food lunch boxes.
Hello！ An ordinary ceramic cup can hold things and can be put into the freezer of the refrigerator. Its disadvantages are brittleness and can not be changed by sudden environmental temperature. (i.e., not just from the refrigerator sometimes hot and sometimes cold, take out, add boiled boiling water, nor just came out from the steamer with, put it in cold water, so are the reasons. The ceramic burst) Ordinary ceramic: using natural raw materials such as feldspar, clay and quartz sintering, is typical of the silicate material, the main ingredients are silicon, aluminum, oxygen, the three elements accounted for 90% of the total crustal elements, the ordinary ceramic rich source, low cost and mature technology. This kind of ceramics can be divided into daily use ceramics, building ceramics, electric insulating ceramics, chemical ceramics and so on according to their performance characteristics and uses. Special ceramics: high purity synthetic raw materials, made of precision control process, shaped and sintered, usually have some special properties to meet the needs of various needs. According to its main components, there are oxide ceramics, nitrides, ceramics, carbides, ceramics, metal ceramics, etc. special ceramics have special mechanical, optical, acoustic, electrical, magnetic, thermal and other properties. This section mainly introduces special ceramics. Ceramic properties, mechanical properties, ceramics, engineering materials is the best stiffness, the highest hardness of the material, the hardness is mostly above 1500HV.
