A pre A*-algebra is the algebraic form of the 3-valued logic. In this paper, we define a binary operation  on pre A*-algebra and show that  is a semilattice. We also prove some results on the partial ordering which is induced from the semilattice. We derive necessary and sufficient conditions for pre A*-algebra (A,Ù,Ú, (-)~) to become a Boolean algebra in terms of this partial ordering and binary operation and also find the necessary conditions for (A , )  as a lattice.


Key words: Pre A*- algebra, poset, semilattice, centre, Boolean algebra.
