What is pure lead sheet? Characteristics and chemical composition of lead plates, pure lead ingots

Pure Lead Sheet is an excellent sealing material for high temperature, gas, steam, pressure transfer liquids and chemicals. It is manufactured from high flakes of natural crystalline graphite, which is processed into continuous film by a special acid and heat…

1. What is pure lead sheet?

  • Lead is a chemical element in the periodic table with the abbreviated symbol Pb, and has the atomic number 82. Pure lead is bluish-white when not exposed to air and changes color to gas gray. contact with the air.
  • Lead has a melting point (327.3 °C) and a boiling point (1750 °C).
  • The density of lead is: 11.3g/cm3.

2. Characteristics of Pure Lead Sheet, Pure Lead Ingot:

  • Excellent thermal stability and reflectivity.
  • Lead has a low temperature resistance of -200°C. High temperature resistance 450°C in air, 700°C in steam.
  • Pure lead has the ability to remove liquid contamination.
  • Low resistivity.
  • High thermal conductivity.

3. Chemical composition of lead ingot, pure lead sheet:

  • Lead is usually produced in two common forms, 99.97%  lead and 99,9%  lead with the corresponding components in the Table of Content Analysis of Lead as follows:
