The axial thermal‐expansion coefficients of β‐eucryptite have been measured and correlated with the volume expansion of an aggregate measured dilatometrically. A mechanical analogy to the structure of β‐eucryptite is suggested which may explain the pronounced thermal contraction in the c direction.
