Silica sand
  DESCRIPTION

Silica sand found in natural, main chemical composition is Silicon Dioxide (SiO2), it has white color. The melting point up to 1700 °C and the specific gravity at 2.5- 2.8, on some source the silica sand content with iron oxide, lime and alkaline as a result it has lower melting point.
Silica sand has quite high thermal expansion at the temperature at 500 - 600 °C because the silica sand change from alpha phase (α ) to beta phase (β) then it has high thermal expansion at this temperature which is dangerous for sand molding.


We can supply silica sand from local and oversea as following
• From local, our silica sand come from Rayong
• From oversea, our silica sand comes from Vietnam and Australia.

 

ORIGIN: Thailand, Vietnam and Australia

 

ADVANTAGE OR BENEFITS:
• High purity of silica content and high melting point.
• Round shape then good molding strength
• Good grain size distribution
• Economic
