Detailed Product Description

Alumina Ceramic Insulator /Electrical Insulation Connector for Battery

 

1. Description:

Now ceramic bodies of porcelain insulators are prepared according to precise recipes that involve compromise in the relative proportions of the different ingredients. End goals include long service life, ease of production and some optimized combination of cost and performance. For example, a typical formulation for porcelain mass contains varying proportions of ball clay, kaolin (for strength and plasticity), feldspar (a flux that helps sintering in the kiln) and fillers such as quartz, alumina or calcined bauxite (intended to impart additional mechanical strength). A variety of secondary materials are also used to facilitate processing, including water and additives such as binders which are burned off in the kiln during firing at up to 1300°C.
