Key Chemical Properties Of Ceramics

Hardness contributing to resistance against wear.

Key chemical properties of ceramics.

Thermal and electrical conductivity considerably lower than that of metals. Advanced ceramics fine ceramics possess good chemical stability. Basically these bonds result in good chemical resistance but have the low thermal expansion high melting point and hardness. Typical properties of ceramics.

Low to medium tensile strength. Great hardness and strength. Different materials have different properties. Low electrical and thermal conductivity they re good insulators.

Ceramics are bonded together by an ionic or covalent bond. High melting points so they re heat resistant. Composite materials combine two or more materials. Mechanical strength in spite of brittleness.

And an ability to take a decorative finish. Ceramic materials are brittle hard strong in compression and weak in shearing and tension. If we re summarizing their properties we can say that ceramics have. Composite materials combine two or more materials.

Considerable durability they re long lasting and hard wearing. A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material. Ceramic tiles are highly resistant to harsh chemical agents like alkalis acids household chemicals and swimming pools salts in high and low concentrations. Polymers are strong and tough and often flexible.

Mass properties e g density ceramics are intermediate density 2 00 6 00 gms cm3 different for allotropes e g glass cristobalite tridymite quartz 2. Polymers are strong and tough and often flexible. Different materials have different properties. High hardness high compressive strength low thermal and electrical conductivity and chemical inertness.

Ceramics are hard and strong but brittle. Ceramics exhibit very strong ionic and or covalent bonding stronger than the metallic bond and this confers the properties commonly associated with ceramics. Melting points high 600 4000c thermal conductivities are low insulators thermal expansion values are low 1 15 ppm c 3. The properties of ceramics make fracturing an important inspection method.

Low to medium thermal conductivity. High resistance to corrosion and chemical attack. Some elements such as carbon or silicon may be considered ceramics. Chemical inertness they re unreactive with other chemicals.
