Key Chemical Properties Of Ceramics

High hardness high compressive strength low thermal and electrical conductivity and chemical inertness.

Key chemical properties of ceramics.

Typical properties of ceramics. Some elements such as carbon or silicon may be considered ceramics. Ceramics exhibit very strong ionic and or covalent bonding stronger than the metallic bond and this confers the properties commonly associated with ceramics. And an ability to take a decorative finish.

High resistance to corrosion and chemical attack. Low to medium tensile strength. Ceramic materials are brittle hard strong in compression and weak in shearing and tension. The properties of ceramics make fracturing an important inspection method.

Ceramics are bonded together by an ionic or covalent bond. Basically these bonds result in good chemical resistance but have the low thermal expansion high melting point and hardness. Considerable durability they re long lasting and hard wearing. Composite materials combine two or more materials.

Different materials have different properties. Mechanical strength in spite of brittleness. These structures and chemical ingredients though various result in universally recognized ceramic like properties of enduring utility including the following. A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material.

Chemical durability against the deteriorating effects of oxygen water acids bases salts and organic solvents. Polymers are strong and tough and often flexible. Ceramics are hard and strong but brittle. Advanced ceramics fine ceramics possess good chemical stability.

Melting points high 600 4000c thermal conductivities are low insulators thermal expansion values are low 1 15 ppm c 3. Chemical inertness they re unreactive with other chemicals. Hardness contributing to resistance against wear. Ceramic tiles are highly resistant to harsh chemical agents like alkalis acids household chemicals and swimming pools salts in high and low concentrations.

Low electrical and thermal conductivity they re good insulators. Different materials have different properties. Composite materials combine two or more materials. If we re summarizing their properties we can say that ceramics have.

High melting points so they re heat resistant. Great hardness and strength. Ceramics are hard and strong but brittle. Thermal and electrical conductivity considerably lower than that of metals.
