Electrical ceramics

Kiln furniture [batts, trays, saggars, props, setters, spacers, etc.] used in the firing of electrical ceramics such as substrates, titanates, electrical powders, ferrites,  spark plugs and electro-porcelains.

High purity fused mullite & high alumina refractories for kiln furniture.

Sandwich (mullite coated silicon carbide) tiles for ferrite manufacture.

Vulcan also manufactures linings for the furnaces and kilns used to manufacture electrical ceramics.electricalceramics2

Application dependent; very high purity and low free silica contents, ability to withstand temperatures up to 1750°C, excellent  high temperature creep resistance, good strength, tight tolerances, flexible shape capabilities, good surface finish
