High Electrical Resistance Ceramics

The interconnection and the amorphous nature of the grain boundary phase resulted from spark plasma sintering both contributed to the improvement of the electrical resistivity.

High electrical resistance ceramics.

Lanthanum yttrium barium copper oxide ceramic may be superconducting at temperature as high as 138 k. Most ceramics resist the flow of electric current and for this reason ceramic materials such as porcelain have traditionally been made into electric insulators. Aluminum nitrides aln are used in many. Silcarb manufactures high alumina ceramics from the range of 92 to 99 as with standard sizes and as per customer requirement.

Electrical resistivity as high as 3 52 10 11 ω cm of sic ceramic was obtained by spark plasma sintering with al 2 o 3 and er 2 o 3 as sintering additives. Steatite has very good electrical resistance properties which are retained at high temperatures and also it has low dielectric loss factor. They also provide excellent electrical insulation properties. Electrical resistance ceramics products find electrical resistance ceramics products manufacturers suppliers and exporters.

Some ceramics however are excellent conductors of electricity. Despite of very low electrical conductivity of most of the ceramic materials there are ceramics possessing superconductivity properties near to zero electric resistivity. The ceramic tiles we manufacture have high hardness good wear resistance high melting point high hardness and high mechanical strength.
