摘要： A composition to produce an adherent and water insoluble deposit on substrate surfaces. A coating material for these surfaces is described which can be applied at any temperature up to at least 2000 degrees F., with the resultant deposit being highly adherent and water insoluble after short drying times. This coating has a liquid phase formed from at least water, a pre-reacted lithium silicate, and a pre-reacted potassium silicate. It can also contain a sodium silicate. This coating can be expressed as being about 69 to about 79 wt. % water and about 21 to about 31 wt. % a mixture of R.sub.2 O and SiO.sub.2. The R.sub.2 O is selected from either a mixture of Li.sub.2 O and K.sub.2 O or from a mixture of Li.sub.2 O, K.sub.2 O and Na.sub.2 O. The R.sub.2 O and SiO.sub.2 typically have a molar ratio of about 0.24 to about 0.29, and the K.sub.2 O is about 35 to 85% of the total molar amount of the R.sub.2 O. When Na.sub.2 O is present, it is up to about 10% of the total molar amount of the R.sub.2 O. To this liquid phase is added a suitable pigment or other refractory material, at about 6-80 wt. % based upon the liquid phase. A range of compositions is discussed as well as typical results.

摘要： A composition to produce an adherent and water insoluble deposit on substrate surfaces. A coating material for these surfaces is described which can be applied at any temperature up to at least 2,000 degrees Fahrenheit, with the resultant deposit (after drying) being highly adherent and water insoluble. This coating has a liquid phase formed from at least water, a pre-reacted lithium silicate, and unreacted lithium hydroxide monohydrate. Preferably, the liquid phase contains a dispersent in the form of a clay, for example. Typically the pre-reacted Li.sub.2 O-SiO.sub.2 has a SiO.sub.2 :Li.sub.2 O molar ratio of about 4.6:1, and the unreacted LiOH.H.sub.2 O provides from 1/3 to 2/3 the total lithium oxide content, giving a final SiO:Li.sub.2 O molar ratio of the composition of from about 1.71:1 to about 2.97:1. To this liquid phase is added a suitable pigment or other refractory material, at about 6-80 wt % based upon the liquid phase. A range of compositions is discussed as well as typical results. This includes graphite, oxides, borides, nitrides, carbides, sulfides, metals and mixtures thereof. The particular refractory material must be stable in the highly basic condition of the liquid phase.

摘要： A binder/suspension liquid for use with refractory compounds and the like. Oxidation prevention coatings for up to at least 1000 degrees Centigrade are described. Both a graphite non-conductive and a conductive coating are described for use in coating graphite crucibles, graphite electrodes, and the like. Typical compositions utilize a binder/suspension liquid phase in an amount from about 40 to about 55 wt. % of the total paintable mixture. This binder/suspension liquid phase is formed by intimately mixing colloidal silica solution, mono-aluminum phosphate solution and alcohol. The non-conducting embodiment of the graphite coating is produced by mixing finely divided boric acid and silicon carbide with the binder/suspension liquid phase. The preferred conductive coating substitutes a mixed TiC-SiC for the SiC of the non-conductive embodiment. The resultant material is very stable (i.e., does not settle), is paintable upon the graphite, and is easily dried at or near room temperature. A few thin coats, with drying between applications, totaling only about 0.15 to about 0.23 mm prevents detrimental oxidation through several cycles to at least 1000 degrees C. Other applications of the binder/suspension agent are discussed.

摘要： A sintered metal ceramic crucible suitable for high temperature induction melting of reactive metals without appreciable carbon or silicon contamination of the melt. The crucible comprises a cast matrix of a thermally conductive ceramic material; a perforated metal sleeve, which serves as a susceptor for induction heating of the crucible, embedded within the ceramic cast matrix; and a thermal-shock-absorber barrier interposed between the metal sleeve and the ceramic cast matrix to allow for differential thermal expansions between the matrix and the metal sleeve and to act as a thermal-shock-absorber which moderates the effects of rapid changes of sleeve temperature on the matrix.

摘要： A relatively chemically inert ceramic material produced from a clay-like mixture of boron nitride powder and aluminum oxide, where the aluminum oxide is derived from colloidal aluminum oxide, peptized aluminum oxide, or a dissolved aluminum salt. The clay-like mixture can be dried in a near net shape without cracking and then pressure-less sintered, or bulk dried. Alternatively, pressure-less sintered bodies can be easily machined to a given shape. The ceramic has properties very similar to those of boron nitride in that it resists damage from molten materials, has a high electrical resistance, has high strength at ambient and elevated temperatures, etc. A typical pressure-less sintered body is formed from a clay made with finely-divided boron nitride mixed with at least one of the listed sources of aluminum oxide such that the final sintered composition contains about 85 wt. % boron nitride.

摘要： A carbon material is formed by heat-treating a carbonaceous material in a reaction mix of oxides of boron and boron nitride in a nitrogen atmosphere to temperatures of 1600 to 2000° C. The surface of the carbonaceous material is transformed into a carbon material that is resistant to oxidation to temperatures of 900° C., enabling machined components to be utilized for weeks at that temperature. The carbon material is also stable in inert or vacuum environments to temperatures in the range of 1500 to 2000° C., enabling its use as aluminum evaporative boats and the like.
