Abstract: 
A weak congruence is a symmetric, transitive, and compatible relation. An element u of an algebraic lattice L is Δ-suitable if there is an isomorphism κ from L to the lattice of weak congruences of an algebra such that κ(u) is the diagonal relation. Some conditions implying the Δ-suitability of u are presented.
