Abstract: A composition comprising A) an aqueous solution wherein the total content of 3-isothiazolinones is below 8 wt/%, and B) a stabilizing compound of the formula: [RxA—C6H2R1R2]y—Z wherein: R, R1 and R2 each independently represents hydrogen, a straight-chained or branched or cyclic alkyl radical, aralkyl or aryl; A is oxygen or nitrogen; Z represents ARx, R1, R2, alkoxy methylene, methylene or alkylidene; provided that when A is oxygen, x is 0 or 1 and when A is nitrogen, x is 1 or 2; and y is 1 or 2; exhibits improved stability.

Abstract: Method for the manufacture of bonded and self-bonded bodies from certain particulate ceramic oxides or carbides by heating a shaped mixture containing the particulate ceramic material and from 1 to 10 percent of its weight of an additive which includes an organic moiety and an inorganic moiety and is non-polymeric in respect of the inorganic moiety, and undergoes decomposition on being heated under atmospheric pressure, said additive being exemplified by such organic compounds as aluminum-dibutyl phosphate; tris-(trimethylsiloxy)-aluminum; and diethyl-(triethoxy-silyl)-vanadate, to produce, by the thermal decomposition, an inorganic residue which remains substantially non-volatile up to temperatures at which the particles of the particulate ceramic material become self-bonding; the mixture containing the particulate ceramic material and additive being fired to a temperature of about 200.degree. to about 600.degree.
