Позорная война рф против Украины

Начата 20 февраля 2014 и полномасштабно продолжена 24 февраля 2022 года. С первых же минут рф ведет ее с нарушением законов и правил войны, захватывает атомные станции, уничтожает бомбардировками мирное население и объекты критической инфраструктуры. Правители и армия рф - военные преступники. Все, кто платит им налоги или оказывают какую-либо поддержку - пособники терроризма. Народ Украины вас никогда не простит и ничего не забудет.

The process of graphitization of anthracite as a carbon component of self-baking electrodes is considered. Experimental studies of the physical properties of thermoanthracite by thermogravimetry and IR spectroscopy in the temperature range 400…1400 °C were performed. Regression models of the relationship between the structure of thermoanthracite, strength, thermal conductivity and resistivity and the temperature regime of anthracite calcination were created. Ref. 9, Tabl. 4, Fig. 7.
