Abstract
During the study of physical properties of four samples of iron meteorites in electric arc furnaces the temperature dependence of kinematical viscosity ν( t ), surface tension σ( t ) and density d ( t ) were investigated. The authors have obtained the diagrams of these dependences for each sample in the range of up to 1800 °C. The obtained data confirm numerous published data on iron and iron-nickel alloys of the Earth origin. It is shown that it is promising to use these characteristics to study space objects, primarily «iron» meteorites, as adequate parameters in investigation of physical properties of meteoric matter, including possible obtaining of alloys with desired characteristics from them. These results support the hypothesis of single origin, development and formation of space objects, at least in the Solar system. It can be used in foundation of space metallurgy, such as in the Earth orbit, on the Moon, on Mars or other Solar system objects.

Summary
При исследовании в электропечах физических свойств четырех образцов «железных» метеоритов изучены температурные зависимости кинематической вязкости, поверхностного натяжения и плотности. Что перспективно использовать эти характеристики для изучения космических объектов (прежде всего – «железных» метеоритов) как адекватные параметры при изучении физических свойств метеоритного вещества, в том числе для получения из них сплавов с заданными характеристиками. Гроховским (ФТИ УрФУ, Екатеринбург) четыре фрагмента метеоритов: Сихотэ-Алиньского метеоритного дождя, метеоритов Чинге и Дронино, «железного» метеорита с включениями оливина, характерными в основном для каменных или железо-каменных метеоритов.
