Catalytic decomposition of potassium chlorate
Journal of Thermal Analysis, 1994Thermal decomposition of potassium chlorate in the presence of various additives is studied using thermogravimetric analysis and differential thermal analysis. Catalytic effects of metal oxides with comparable surface areas are compared, and the catalytic effects of a number of nonoxide additives are also studied.

Is potassium chlorate a ferroelastic?
Acta Crystallographica Section A, 1980New twin domains of thickness of the order of a few micrometres can be created in KClO3 crystals by applying a small uniaxial stress. The observed domain structure can be explained by postulating a hypothetical prototype phase of symmetry 4/mmm. The magnitude of spontaneous strain, σs, for the room-temperature monoclinic phase, computed on the basis of

Thermal Expansion of Potassium Chlorate
Proceedings of the Physical Society. Section B, 1955The principal coefficients of expansion and the orientation of the ellipsoid of expansion have been determined for potassium chlorate for the ranges 30 to 90, 90 to 150 and 150 to 200°C. An x-ray method was used and the expansion coefficient in the directions normal to the various planes in the zones [100], [010] and [001] were determined by recording ...

Colour centres in potassium chlorate, KClO3
Journal of Physics and Chemistry of Solids, 1967Abstract The absorption spectrum of a X-ray irradiated KClO 3 crystal is reinvestigated and the results are discussed in relation to the earlier work. A new band with a sharp peak at 218 mμ is reported and attributed to be due to perturbation of the fundamental absorption of the crystal by the presence of point defects.

Polarized Vibrational Spectra of Potassium Chlorate
The Journal of Chemical Physics, 1971The Raman spectra of single crystal KClO3 were measured in the region above 30 cm−1 at 298 and 77°K. Single crystal infrared spectra in the internal mode region were measured by reflection at 298°K. Infrared spectra of the polycrystalline material also were measured at 77°K.

ISOTHERMAL AND ISOPIESTIC DECOMPOSITION OF POTASSIUM PERCHLORATE AND POTASSIUM CHLORATE*
Annals of the New York Academy of Sciences, 1960Samples of purified potassium perchlorate were decomposed at various constant pressures of air or oxygen and at various constant temperatures from 555 to 590 deg C. A number of differential thermal analyses of potassium chlorate was made in which the runs were stopped at various temperatures ranging from 330 to about 600 deg C.

A CASE OF POTASSIUM CHLORATE POISONING
Journal of the American Medical Association, 1911Damage by borrowed medicine is frequently met. The following is an instance: May 21, 1911, I was called to see a twenty-day-old baby with the following history: The mother knew of a neighbor's having some medicine that I had prescribed about a year previous for sore mouth, borrowed it and used it in large amounts locally on the membrane of the baby's ...

On the iridescence of potassium chlorate crystals
Proceedings of the Indian Academy of Sciences - Section A, 1952Spectrograms obtained with five iridescent crystals of potassium chlorate at varying azimuths and obliquities of incidence have been obtained and are reproduced with the paper. Some of the results observed are explicable in terms of the general theory of the optical behaviour of a regularly stratified medium,viz., (a) the appearance of a whole series ...
