Alumina ceramic rod heating production

Product Description

Ceramic Rod properties:

      1. Thermal performance The most important performance of ceramic materials is thermal performance, usually has a very high melting point (mostly above 2000℃), and has a strong chemical stability at high temperature. Ceramic is also a good insulation material, its coefficient of linear expansion is lower than metal, even when the temperature changes, it is also very stable performance.

      2. Electrical And Electronic Ceramic materials have good electrical insulation, so they are often used to make various voltage insulation devices. Ferroelectric ceramics have high dielectric constant, which can be used to make capacitors. Under the action of external electric field, ferroelectric ceramics can also change shape, convert electric energy into mechanical energy (with the characteristics of piezoelectric materials), which can be used as record players, ultrasonic meters, medical spectrometers, etc.

     3. Chemical properties ceramic material chemical performance is also very good, it is not easy to oxidation at high temperature, and has good corrosion resistance to acid, alkali, salt.

     4. Mechanical properties of engineering materials have the best stiffness and highest hardness, most of which are above 1500HV. Ceramics have high compressive strength but low tensile strength, poor plasticity and toughness.
