Porcelain or ceramics usually have a combination of stronger bonds called ionic and covalent .The strength of an ionic bond depends on the size of the charge on each ion and on the radius of each ion. The greater the number of electrons being shared, is the greater the force of attraction, or the stronger the covalent bond. These types of bonds result in high elastic modulus and hardness, high melting points, low thermal expansion, and good chemical resistance. However, ceramics are also hard and often brittle which lead to fracture.
