An insulation assembly is provided, including: a body of an insulating material with a lower surface configured to contact a sidewall an electrolysis cell; an upper surface generally opposed to the lower surface; and a perimetrical sidewall extending between the upper surface and the lower surface to surround the remainder of the body, the perimetrical sidewall including: an inner portion configured to face an anode surface of the electrolysis cell and provide a gap between the body and the anode surface of the electrolysis cell; wherein the body is configured to extend from the sidewall towards the anode surface.

Insulation assembly for electrolysis cell

A method of making an inert anode (') for use in an electrochemical cell first provides a hollow shaped mold () where a metal mandrel (&#x2032;) having raised male threads () at its top diameter () is inserted into the mold () and a compressible powder () added, then the powder is compressed to form recessed female grooves () matching the mandrel threads () where the mandrel (&#x2032;) is engaged and withdrawn along with the compressed powder inert anode after which the mandrel is rotated to unscrew it from the compressed powder and the compressed powder shape is then placed on a tray () and heated to sintering temperature.
