Abstract: Clayware is produced by firing a composition containing clay and a boron-containing flux, wherein the flux is a synthetic alkali metal and/or alkaline earth metal aluminosilicate having the crystal structure of a zeolite and containing boron entrapped within that structure. The boronated zeolite flux can be prepared in a form in which it can be used directly in the manufacture of clayware, especially earthenware.
Abstract: Molybdenite is recovered by froth flotation of ore or concentrate by use of thio carboxylic acid compound and activated carbon to depress copper and other metal sulfides. The reagents are preferably utilized in a weight ratio of about 1:1.

Abstract: Alkali metal borates are reacted with fatty acids or oils in the presence of a low HLB value surfactant to give a stable, mineral oil-soluble product. Mineral oil containing the borate can be used as a cutting fluid.
Abstract: Method of anodizing aluminum by subjecting it to electrolysis, first in a bath of electrolyte containing a borate and then in a bath of electrolyte containing an acid. Preferably, the electrolyte in the first bath is about 3-5% borax with the pH adjusted to about 9 to 11 by addition of sodium hydroxide.The method forms an oxide coating which is of sufficient depth to comply with normal specifications and which also does not suffer from alkaline staining.

Abstract: Compounds comprising three atoms of a divalent metal linked through oxygen atoms to an atom selected from the group consisting of a boron atom, a phosphorus atom and a phosphorus atom bonded to an oxo oxygen, and an aliphatic monocarboxylic acid radical attached to each divalent metal atom, at least one of said aliphatic monocarboxylic acid radicals having from 7 to 9 carbon atoms, and at least one other of said aliphatic monocarboxylic acid radicals having 10 or 11 carbon atoms, and the polymerization products thereof, are useful as rubber compound adhesion promoters and are more easily handled than the previously known compounds and polymers used for this purpose.
Abstract: Bone china is produced by including a boron-containing substance in the composition in water-insoluble form. Use of the boron-containing compound results in a lowering of the firing temperature and widening of the firing temperature range.
