Ceramic coating a car makes water bead right off, but the best brake pads and clutches are also ceramic (aside from carbon ceramic and carbon carbon)
Answered: basically ceramic is a wide range of materials with vastly different properties
Ceramic comes from the word Keramic which means relating to Pottery.
If you mix sediments with moisture and fire it in an oven, it is ceramic. Difference of materials means different properties. Some materials crystalize, some burn, or some polish smooth easily.
To put it simple: fine china is ceramic, but so are bricks.
Well, the bottoms of cleets are friction-inducing surfaces, but unless you pour a LOT of soda onto them, they ain’t gonna be sticky.
It’s as simple as that.
Ceramics are a broad class of materials with a wide spectrum of properties. There is no one singular material called “ceramic.” Ceramic materials can be made smooth and slippery or textured and grippy, and everywhere in between.
Included in that range are both terracotta and bone China which are radically different materials.
Because ceramic is an extremely vague term - as a parallel you can look at carbon which can be crumbly and a good fuel, one of the hardest materials on earth or a variety of other forms.
guess so, i thought ceramic would just be one thing but yeah that makes sense
Quoting Wikipedia in reference to the variance in ceramics for the degree of crystallinity and number of electrons in their iconic and covalent bonds:
With such a large range of possible options for the composition/structure of a ceramic (nearly all of the elements, nearly all types of bonding, and all levels of crystallinity), the breadth of the subject is vast, and identifiable attributes (hardness, toughness, electrical conductivity) are difficult to specify for the group as a whole
