Certain derivatives of the lanthanide elements greatly enhance the strength of heated alumina refractories in the 500 to 1000 degree Fahrenheit temperature range. Cerium oxide, for example, when added in 1 percent to 5 percent by weight to commercial calcium aluminate cement with tabular alumina aggregate, plus 10 to 30 percent water, and fired at 500 to 1000 degrees Fahrenheit, forms a ceramic bond and becomes as strong as untreated calcium aluminate refractory concrete fired at 2000 degrees Fahrenheit. The cerium modified refractory concrete is 1000 psi to 1500 psi stronger than unmodified refractory concrete at 500 to 1000 degrees Fahrenheit.

Mixed metal chalcogenides formed of lanthanide chalcogenides having the formula MLnX. sub. 2 where M is selected from the group consisting of Ag, Cu and Au; Ln is one of the elements of the lanthanide family other than Pm and X is selected from the group consisting of S, Se and Te and having electrical properties that range from dielectrics to semiconductors to metallic conductors in a temperature range from -50. degree. C. to in excess of +100. degree. C. The lanthanide chalcogenides can be prepared by slow fusion of the basic elements such as silver, lanthanum and selenium, in substantially stoichiometric properties, in powder form under an extended time period at elevated temperature, e. g. 650. degree. C. to 700. degree. C.

A color changing pigment composition which changes color reversibly when ted comprising (a) a cyclic aryl lactone dye, (b) a diaminoalkane activator and (c)an ester. The pigment composition can also include a white pigment such as titanium dioxide as an opacifier or a yellow dye such Hansa yellow G. The pigment composition changes from a dark color, e. g. blue, to white when the composition is heated to a specified temperature, e. g. to a temperature of 52. degree. C. , and reversibly changes from white back to the blue color when the pigment composition is cooled, e. g. to a temperature below about 25. degree. C.

A portable infrared spectrophotometer for nondestructive testing of coatings, plastics, rubber and other organic construction materials. A single source of infrared light is formed into two beams. One beam is directed to the surface of a sample where it is reflected off the surface of the sample at least four times. The other beam follows a similar path but bounces off a neutral surface. The two beams are combined and focused onto a detector. The output of the detector is proportional to the energy absorbed by the surface of the test sample. A pen recorder is used to provide a graphic display of the spectrum generated.

A series of chemically synthesized compounds known as metal mercury iodides or metal tetraiodomercurates having use as infrared detectors are made by reacting potassium tetraiodomercurate(II) with monovalent metal nitrates or iodides, such as thallium(I), indium(I) or copper(I) nitrates. In the case of gold, the gold(I) iodide is used because the nitrate is not known. The precipitated metal (thallium, indium, copper, gold, etc. ) tetraiodomercurate is then filtered, dried, and purified (recrystallized) and pressed into a disk under high pressure. Alternatively, the material can be grown as a large crystal by zone melt fusion methods.

A significant increase in the structural strength of heated calcium alumie refractory products, such as mortar and concrete, can be obtained by the addition of alkaline earth borates, barium metaborate in particular, and heating in the range of 500 to 1000 degrees F. to cure the refractory, with an optimum strength provided at approximately 750 degrees F.
