LAB ISOSTATIC CHAMBER FOR ANALYSIS OF COMPOSITIONS Russian patent published in 2010 - IPC B22F3/15 

FIELD: process engineering.

SUBSTANCE: invention relates to equipment intended for analysis and production of compositions at high pressure and temperature and can be used for compacting granules and compounds by fluids and gases. Proposed isostatic chamber comprises primary container tightly closed by sealed top and bottom plugs, one of said plugs being communicated with gas pressure source, that make work chamber. Said work chamber accommodates heater and heat isolating cap secured on top plug, work table arranged on bottom plug and vessel for composition to be analysed arranged on said table. Note here that said heater, cap and bottom plug are arranged with end face gap filled with heat isolation. Cap and heater, heater and work table are arranged with a minimum radial gap. Besides a flexible high-temperature electric insulation is laid between heater and cap. Note here also that said cap incorporates variable-thickness isolation over its height that reduces toward the cap top part.

EFFECT: uniform heating over chamber height, reduced heat losses and increased removal of excess heat.
