Weight Conversion Table Dielectric Constant of Solutions The relative permittivity, or dielectric constant, is a dimensionless material property which represents a material's dielectric permittivity as a ratio relative to the permittivity of a vacuum. The relative permittivity, or dielectric constant, of a material is its (absolute) permittivity expressed as a ratio relative to the vacuum permittivity.. Permittivity is a material property that affects the Coulomb force between two point charges in the material. ; Solubilities are in water and are reported as grams solvent/100 grams water. of Dielectric Constant where •,, 1, and a (or a if the value is followed immediately by a in parentheses) are specified in Values of dielectric constant recorded in sections the table. List of Dielectric Constants The following list of dielectric constants is based on approximate values for the substance listed in its natural state. List of dielectric constants Substance Substanz Dielectric Constant Rapeseed grist Raps-Schrot 2,1 Resin Harz 1,5 Rice Reis 3,0 Rock salt (0-25 mm) Steinsalz (0-25 mm) 4,3 Rye Roggen 6,0 Rye bran Roggenkleie 2,2 Saccharose solution Saccharoselösung 20,0 Salt water Salzwasser 32,0 Dielectric constant is defined as the insulating material that can store charge when it is placed between two metallic plates. Relative permittivity is the factor by which the electric field between the charges is decreased relative to vacuum. Dielectrical Constants of Polymers; Compound: ε (Exper. ): ε (Calc. All other factors being equal, greater permittivity of the dielectric gives greater capacitance; less permittivity of the dielectric gives less capacitance. The table of GPR velocities, dielectric constants, and conductivity values is a culmination of resources comparing values reported by government agencies and sources easily accessed by the public. Values presented here are relative dielectric constants (relative permittivities). The chart is intended to provide a comparison of how the GPR velocity of a material can range between sources. Dielectric constant is a measure of the charge retention capacity of a medium. The dielectric constant is expressed in terms of a ratio to that in a vacuum or (1.000000). In the table are given the values of the dielectric constant of some solids, liquids and gases for constant electric fields or for small frequencies, when the wavelength is infinitely large. Multiply by ε 0 = 8.8542 x 10-12 F/m (permittivity of free space) to obtain absolute permittivity. Notes: In 2005, this table was adapted by Dr. Brian J. Myers, Webmaster of ACS Division of Organic Division (DOC) from: Professor Murov's Organic solvent table.The values were obtained from the CRC (87th edition), or Vogel's Practical Organic Chemistry (5th ed.). It is also known as electric permittivity. The following table lists the dielectric constants … As indicated by e r = 1.00000 for a vacuum, all values are relative to a vacuum..
