✦ Synopsis

A new phase, of probable composition CavSiz60,oH=, has been prepared hydrothermally from CaO and silicic acid in silica rich mixes at temperatures around 375°C.

It is structurally closely related to truscottite, from which it is derived by taking one of the two types of silicate layer without the other.

Analytical and unit cell data are presented, together with the probable crystal structure and calculated X-ray powder diffraction pattern.
