Key Chemical Properties Of Ceramics

Polymers are strong and tough and often flexible.

Key chemical properties of ceramics.

Low to medium thermal conductivity. Chemical durability against the deteriorating effects of oxygen water acids bases salts and organic solvents. Composite materials combine two or more materials. High melting points so they re heat resistant.

Considerable durability they re long lasting and hard wearing. 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. A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material. And an ability to take a decorative finish.

These structures and chemical ingredients though various result in universally recognized ceramic like properties of enduring utility including the following. Ceramics are hard and strong but brittle. Ceramic tiles are highly resistant to harsh chemical agents like alkalis acids household chemicals and swimming pools salts in high and low concentrations. Chemical inertness they re unreactive with other chemicals.

If we re summarizing their properties we can say that ceramics have. Ceramics are hard and strong but brittle. Mechanical strength in spite of brittleness. Melting points high 600 4000c thermal conductivities are low insulators thermal expansion values are low 1 15 ppm c 3.

Composite materials combine two or more materials. Thermal and electrical conductivity considerably lower than that of metals. Basically these bonds result in good chemical resistance but have the low thermal expansion high melting point and hardness. Typical properties of ceramics.

High resistance to corrosion and chemical attack. The properties of ceramics make fracturing an important inspection method. Hardness contributing to resistance against wear. High hardness high compressive strength low thermal and electrical conductivity and chemical inertness.

Ceramics are bonded together by an ionic or covalent bond. Low electrical and thermal conductivity they re good insulators. Ceramics exhibit very strong ionic and or covalent bonding stronger than the metallic bond and this confers the properties commonly associated with ceramics. Low to medium tensile strength.

Great hardness and strength. Ceramic materials are brittle hard strong in compression and weak in shearing and tension. Different materials have different properties. Different materials have different properties.
