| Steatite bodies were developed using Jaipur talc and small amounts of barium
and magnesium carbonate as bonding agents. The bodies were tested for shrinkage,
absorption, density, thermal expansion, thermal endurance and electrical propertiJes
including dielectric strength, DC resistivity, power factor and loss fact.or. Effect
of replacing barium carbonate by magnesium carbonate and lead silicate was also
studied. Some of the compositions conform to the A.S.A. spedfications for the
highest grade of low-loss insulators. |
