| Magnesium oxychloride and magnesium oxysulfate materials and methods of making the same are disclosed. The materials are cured reaction products of a magnesium oxide, and an aqueous magnesium salt solution. The aqueous salt solution preferably has a specific gravity of about 1.18 to about 1.4. The magnesium oxide has a platelet or flake structure, a bulk density of about 30 lbs/ft3 (about 0.48 g/cm3) to about 70 lbs/ft3 (about 1.12 g/cm3), and a particle density of about 215 lbs/ft3 (about 3.45 g/cm3) or less. The platelet/flake magnesium oxide is prepared, preferably from particles of magnesium oxide ore or brucite ore, using brine-free methods. | ||||||
| 43 | Composition and method of producing insoluble mag-oxy cements | US176629 | 1980-08-11 | US4312674A | 1982-01-26 | Joseph P. Stalego; Ernest E. Lawson |
| Mag-oxy cements are made by either molding or heat treating after molding at elevated temperatures. The products are made utilizing colloidal silica and/or phosphates and the products are made by either molding or by heat treating after molding at elevated temperatures.The products treated at 250.degree. F. show considerably less solubility particularly where both phosphates and silicates are present in which case the weight loss based on the reactables may be as low as approximately 2 percent. When heat treated at 300.degree. F., there is no weight loss in practically all cases; but a pickup in weight occurs indicating an additional hydration. Sheet molding compounds are also made by processes which provide a deficiency of water of hydration. | ||||||

| Cementitious magnesia compositions are disclosed containing at least one of a family of organo-silicon compounds, each of which is characterized in having attached to the silicon atom at least one group hydrolyzable at the silicon atom and at least one group comprising a moiety that is attached to the silicon atom through a substantially non-hydrolyzable silicon-carbon bond. Magnesia compositions containing one of the described organo-silicon compounds, wherein the non-hydrolyzable moiety has a working parameter of solubility, .delta..sub.wp, typically in the range of about 6.2 to about 8.0 (cal./cc).sup.1/2, have improved casting, molding or spraying properties as compared to magnesia compositions lacking the organo-silicon compound. | ||||||

| A method of incorporating a material in a settable binder is disclosed. The binder includes a source of caustic magnesium oxide. The method involves mixing the material with the binder, either as part of a slurry or for subsequent formation into a slurry, and then adding a setting agent to the slurry. The setting agent is added to enhance setting of the binder. The material can be a hazardous waste material or components thereof. The inventors have surprisingly discovered that when the setting agent is added after mixing of the material with the binder, that a superior setting of the material in the binder can be achieved. The settable composition can comprise only a caustic magnesium oxide binder and a setting agent for the binder, as the inventors have surprisingly discovered that there is no need for any other binding agents, thus providing a simpler binder composition and method of use. | ||||||

An all-purpose two-component adhesive material and a process for its production that can be used both for fastening together flexible and porous material, such as for example wood, plastics, fabric, as well as for joining stiff material such as metal, stone. In particular the process can also be carried out using as reagents compounds resulting from processes of neutralization of exhausted sulphuric acid. In large amount adhesive material can be used to make coating material, such as tiles, whereas in different concentration the adhesive material can be used as fire-retardant varnish. The adhesive material is formed by: a first component that is an aqueous solution, having concentration higher than 5% in weight, of a sulphate, chloride, nitrate, acetate of magnesium or zinc; and a second component that is a mixture of magnesium oxide MgO, metal hydroxides, calcium sulphate hemi-hydrated. The magnesium or zinc salt are chosen among MgSO4, MgCl2; MgNO3; Mg(CH3COO)2, ZnSO4, ZnCl2; ZnNO3; Zn(CH3COO)2. In the second component the metal hydroxides are chosen among Mg(OH)2; Al(OH)3; Fe(OH)3; Ti(OH)4. |
