  There are two processes for
  preparing water glass that are
  common this day. The first one is
  by reaction in liquid phase while
  the next one is by reaction in
  solid phase. However, alkaline
  and
  quartz sand are the same raw
  materials used in the two
  processes.
  1. Process with reaction in
  liquid
  phase: Caustic soda, quartz sand
  and water are mixed in a mixing
  tank, and then the mixture is fed
  into a reactor, where steam is
  introduced. The reactant is
  liquid
  water glass with its module lower
  than 3. The reaction is as
  following: nSiO2+2NaOH
  Na2O.SiO2+H2O
  2. Process with reaction in solid
  phase (thermal process) The feed
  materials in this process are
  sodium carbonate and quartz sand,
  or sodium sulfate and quartz
  sand.
  The feed materials are heated in
  a
  reflection furnace. The reaction
  is as following: Na2CO3 +XSiO2 →
  (Na2O)(SiO2)X + CO2 4Na2SO4 +2C
  +4SiO2→ 4Na2SiO3 +4SO2 +2CO2 The
  water glass produced by this
  thermal process can have modules
  depending on requirements for
  different applications.
