          Ceramic heating core technical parameter:
          First, the material and so on takes the parent metal by the aluminum oxide ceramics material, produces the heating pore ceramics.
          Second, heating material, hard chromium aluminum alloy material:
          The specification for the resistance 1.1~1.3 ohms, the lead wire, line diameter 0.22~0.27mm, the circle high 3.0~3.5, the turn 5~6, gives off heat silk thread diameter 0.16~0.19mm.

          Attaches the pore ceramics, the hole, the aperture, the report in addition is as follows:

          Open factor of porosity

          Water-absorptivity

          Volume density 

          Opens the hole volume

          Seal factor of porosity

          50~60%

          45~55%

          0.95~1.3g/cm3

          0.03~0.06%

          14~16%
