    摘要： A foundry mold and the method of making it is disclosed and claimed. Black liquor is extracted from a pulping process and used as a resin which when combined with an aggregate forms a foundry mold, foundry core or a briquette. The black liquor can be combined with another material to accelerate the cure and to resist moisturization of the mold, core or briquette.

    摘要： A sand sculpting composition including approximately 100 parts by dry weight of sand, between 0.1 part and 5 parts by dry weight of at least one non-toxic cold water-soluble adhesive agent selected from the group consisting of pre-gelatinized starches, chemically modified starches and chemically modified celluloses, and between 6 and 25 parts by weight water. The adhesive agent has been combined with the sand and an amount of water sufficient to both dissolve the adhesive agent and allow the adhesive agent to coat the particles of sand. A coloring agent may be added to the adhesive agent.

    摘要： A water-soluble ceramic core is prepared which can be advantageously used in the die casting, gravity casting, and investment casting of precision aluminum alloy objects. The ceramic core contains: (a) 60 to 70% by weight of alumina (A1.sub.2 O.sub.3) flour; (b) about 15 to 25 by weight of zircon (ZrSiO.sub.4) flour; (c) about 5 to 15 by weight of sodium hydrogen phosphate (Na.sub.2 HPO.sub.4); and (d) about 5 by weight of sugar. In preparing the ceramic core, sodium hydrogen phosphate and sugar are first dissolved in water to form a sodium hydrogen phosphate/sugar solution. Then alumina flour and zircon flour are added into the sodium hydrogen phosphate/sugar solution to form a slurry, which is caused to form a precursory ceramic core using an injection molding or slip casting process. After blow-drying the precursory ceramic core is calcined at temperatures between 70 and 800.degree. C. The ceramic core can be optionally immersed into a lacquer solution to impart a water-proof film on its surface, so as to allow it to withstand attacks from steam during autoclaving.
