Studies on the Physico-Mechanical and Electrical Properties of Porcelain through Enrichment of Alumina by Substituting Quartz with Calcined Bauxite

In the present study, total quartz content (30 mass-%) of a standard porcelain body was progressively substituted by iron-rich calcined bauxite of Indian source. The compacted samples were fired in the temperature range of 1170–1320 °C and subjected to various tests namely linear shrinkage, bulk density, flexural strength, apparent porosity, deep abrasion resistance, thermal expansion … Weiterlesen …

Microstructural and Electrical Characteristics of Sintered Aluminous Porcelain Insulators

In the present investigation, changes in the microstructural and electrical behaviour of aluminous porcelain insulator bodies with variation of the Al2O3 : SiO2 mole ratio from 0,15–0,70 due to substituting quartz by technical alumina into the parent porcelain composition has been studied during sintering at 1260 °C for 4 h. The profound improvement of the … Weiterlesen …
