| 121 | Hard setting refractory composition | US1573 | 1987-01-08 | US4780142A | 1988-10-25 | Harold L. Rechter |
| Novel compositions are disclosed for the manufacture of gunning mixes and strong castable products for use as monolithic refractory and construction materials which may contain no lime bearing cements. Bonding is based on the setting reaction of fumed silica with an alkali metal silicate preferably a particulate sodium or potassium silicate that slowly dissolves in water such as an anhydrous sodium silicate of SiO.sub.2 :Na.sub.2 O molar ratio of 1:1 to 4:1; or an anhydrated potassium silicate having an SiO.sub.2 :K.sub.2 O molar ratio of 3:1, or a hydrated sodium silicate having an SiO.sub.2 :Na.sub.2 O molar ratio of 3:1. Setting and mechanical characteristics allow this class of castable and gun mixes to be placed more rapidly into service since the time required for curing is much less. Although initial set strengths are not as high as those of conventional castables, very high strengths can be made to occur shortly after setting by heating. The addition of sodium hexametaphosphate was found to be highly beneficial to working and handling characteristics. | ||||||

| 127 | Refractory castables with hydrophobic aggregates | US15248925 | 2016-08-26 | US09751804B2 | 2017-09-05 | Kenneth J. Moody; Bryan K. Doerr |
| Hydrophobic aggregates for use in refractory castables and gunning mixtures and methods of their preparation. The aggregates here are formed by crushing insulating fire brick and coating the resulting particles with a hydrophobic component. The hydrophobic component may be a polydimethylsiloxane having a terminal silanol group. As a result of the coating process, the coated aggregate has very low levels of alkalis. The aggregates may be used to form refractory castables that do not undergo substantial alkaline hydrolysis due to the reduced levels of alkalis. The castables made from these aggregates display superior physical properties, including lower water content, lower permanent linear change, high strength, and superior thermal conductivity/insulation properties, while at the same time possessing lower density and requiring less water to be used during castable formation. These improved properties also are observed in gunning mixtures formed from these aggregates. | ||||||

| A reinforced carbon foam material is formed from carbon fibers incorporated within a carbon foam's structure. First, carbon fiber bundles are combined with a liquid resol resin. The carbon fiber bundles separate into individual carbon fiber filaments and disperse throughout the liquid resol resin. Second, the carbon fiber resin mixture is foamed thus fixing the carbon fibers in a permanent spatial arrangement within the phenolic foam. The foam is then carbonized to create a carbon fiber reinforced foam with improved graphitic characteristics as well as increased strength. Optionally, various additives can be introduced simultaneously with the addition of the carbon fiber bundles into the liquid resol, which can improve the graphitic nature of the final carbon foam material and/or increase the foam's resistance to oxidation. | ||||||
