A microporous crystalline material named zeolite A-LSX having, in its anhydrous form, an oxides molar composition corresponding to formula (I):

Microporous crystalline material, a process for its preparation and its

Stable aqueous suspensions of zeolite 4A which can be easily pumped, containing from 0.5 to 65% of zeolite and from 0.05 to 6 g (per 100 g of zeolite) of a suspending agent, composed of mixtures of ethoxylated alkanols, said mixtures being obtained by ethoxylating: a) biodegradable branched alkanols, having from 10 to 18 carbon atoms and having a single branching in position 2, said mixtures containing at least 2 alkanols having a different number of C atoms; or b) mixtures containing 40-100% of branched alkanols as in a) and 60-0% of linear alkanols having from 10 to 18 C atoms.

Stable aqueous suspensions of zeolite which can be easily pumped

Aqueous suspensions of a silica-based inorganic material insoluble in water and in a finely subdivided form, stabilized with at least one organic polymeric compound containing hydroxylic groups and with an ammonium or phosphonium quaternary compound of the formula: ##STR1## wherein: B is nitrogen or phosphorus; A is either mono or polyvalent anion, while A.sub.1.sup.- is SO.sub.3.sup.- or COO.sup.-.
