Description
Известный способ получени хрома заключаетс в том, что окись хрома восстапавливают карбидом СгуСз плп сажей. Однако этот способ мало эффективен вследствие едлепного протекани реакции.A known method for producing chromium is that chromium oxide is reduced by carbide SluSz plp with soot. However, this method is not very effective due to a single reaction.
Отличительна особенность описываемого способа состоит в том, что окись хрома восстанавливают высшим карбидом хрома (СгзСз) из брикетированной шихты, содержашей 93-95% окиси хрома от стехиометрического состава, иуте.м нагрева шихты в вакууме до 1600°. Полученный хро.м содержит 98-99% хрома. Этот способ позвол ет интенсифицировать нроцесс и уменьшить выделение газов.A distinctive feature of the described method is that chromium oxide is reduced by higher chromium carbide (Cr3C3) from briquetted charge containing 93-95% of chromium oxide from the stoichiometric composition, and i.m. of heating the mixture in vacuum to 1600 °. The resulting hrom.m contains 98-99% chromium. This method allows to intensify the process and reduce the release of gases.
Порошок TexinmecKoio хрома, П1;лученный предлагаемым способом, может найти ирименение в производстве металлокерамических изделий, а также в катализе.Chromium TexinmecKoio powder, P1; obtained by the proposed method can be used in the production of metal-ceramic products, as well as in catalysis.
Предмет изобретени Subject invention
Способ иолучени порошка технического хрома восстановлением окиси хрома карбидом, отличающийс тем, что, с целью интенсификации процесса и уменьшени выделени газов, окись хрома восстанавливают высшим карбидом СгзС2 нагреванием в вакууме при температуре 1600° шихты, содержашей 93-95% Сг2Оз от стехиометрического составаThe method of obtaining technical chromium powder by reducing chromium oxide with carbide, characterized in that, in order to intensify the process and reduce the evolution of gases, chromium oxide is reduced by higher carbide Cr3C2 by heating in vacuum at 1600 ° C, containing 93-95% Cr2Oz from the stoichiometric composition
