Abstract
Способ очистки графитовых изделий, включающий нагрев графитовых изделий в вакууме, подачу хладона-12 и охлаждение в вакууме либо в среде инертного газа, отличающийся тем, что нагрев проводят до температуры 2000°C, затем откачку прекращают, а в зону вводят пары четыреххлористого углерода класса ОСЧ до давления 50 Торр, далее после выдержки в течение 30 мин, проводят откачку реакционных продуктов через азотную ловушку, затем повышают температуру до 2100°C, прекращают откачку и вводят в зону хладон-12 до давления 30 Торр, далее после выдержки в течение 30 мин проводят откачку реакционных продуктов через азотную ловушку, затем осуществляют изотермическую выдержку при 2100°C в вакууме в течение 2 ч, охлаждение проводят в вакууме либо в среде инертного газа.A method of cleaning graphite products, including heating graphite products in vacuum, supplying HFC-12 and cooling in vacuum or in an inert gas medium, characterized in that the heating is carried out to a temperature of 2000 ° C, then pumping is stopped, and carbon tetrachloride vapors of the class are introduced into the zone TSP to a pressure of 50 Torr, then after holding for 30 minutes, pump the reaction products through a nitrogen trap, then increase the temperature to 2100 ° C, stop pumping and introduce HFC-12 to a pressure of 30 Torr, then after holding for 3 0 min. The reaction products are pumped out through a nitrogen trap, then isothermal exposure is carried out at 2100 ° C in vacuum for 2 hours, cooling is carried out in vacuum or in an inert gas medium.
