Tip: Support ceramic pipe processing into internal and external threads, polishing, round head...

Most ceramics have good electrical insulation, so industial ceramics tube are widely used in the manufacture of various insulation devices.industial ceramics tube has a high dielectric constant, can be used to make capacitors, ferroelectric ceramics under the action of the external electric field, but also can change the shape, electrical energy into mechanical energy (with the characteristics of piezoelectric materials),
