About Ettringite
Formula:
Ca6Al2(SO4)3(OH)12 · 26H2O
Colour:
Colourless; colourless in transmitted light.
Hardness:
2 - 2½
Specific Gravity:
1.77

Trigonal
Member of:
Name:
After the type locality at Ettringen, Rhineland-Palatinate, Germany.
Ettringite Group.
Although it is generally assumed that a solid solution series between ettringite and thaumasite exists, both species have different space groups and a possible discontinuity was identified, characterised by a gap in the a-dimension of the solid-solution phases (Barnett et al., 2000). Further work showed a miscibility gap in the solid solution (Barnett et al., 2003): ettringite can accept the replacement of 1/2 its Al by Si, while thaumasite tolerates little or no Al in its structure.
The Al analogue of bentorite. The S (sulfate) analogue of siwaqaite.
Well-known as a synthetic phase in concrete.
Has been discussed as a potential phase for immobilisation of toxic metals.
