What are the dishes in most restaurants that are unbreakable?

Japan Light Metal Company added fine bauxite into ceramic soil to make impact-resistant ceramic tableware, and its strength is 3 ~ 5 times that of ordinary ceramic tableware. Because bauxite particles are very fine, they can absorb impact and prevent cracking, so ceramic tableware made of bauxite will not be broken.

1, generally made of melamine.

2. Melamine plastic tableware (also known as porcelain-like tableware) has the properties of portability, beauty, low temperature resistance (can be directly put into the refrigerator), cooking resistance (can be boiled in boiling water), pollution resistance and not easy to break.

3. Due to the particularity of molecular structure of melamine plastic, melamine tableware cannot be used in microwave ovens.

Most ceramic materials lack plastic deformation ability and toughness, the ultimate strain is less than 0. 1% ~ 0.2%, and they are brittle under external force, and their impact resistance and thermal shock resistance are also poor. The fracture of brittle parts often leads to the destruction of materials. The room temperature plasticity of ordinary ceramic materials is zero, because most ceramic materials have complex crystal structure, few slip systems, high dislocation generation energy and poor dislocation mobility.

Ceramic materials:

Ceramic material is an inorganic non-metallic material made of natural or synthetic compounds through molding and high temperature sintering. It has the advantages of high melting point, high hardness, high wear resistance and oxidation resistance. It can be used as structural materials and tool materials, because ceramics also have some special properties and can also be used as functional materials.
