AL2O3 Aluminum Oxide Ceramic Insulator Seal Ring 3.9g/Cm3 For Power Battery

Alumina Ceramic Insulator /Electrical Insulation Rod For Oxygen Sensor


1. Description:

These various minerals are mined from sites the world over and, since no two locations are alike in all respects, some variation can be expected in raw material quality. This must be considered and controlled during the production process to ensure consistent quality of the final product. In particular, growing attention has been placed on the microstructure of these raw materials to avoid development of undesirable interfaces at the microscopic level. For example, experts believe that quartz crystallites found in some ceramic aggregates can feature critically over-sized particles that modify and shrink during firing. Resultant micro-cracks can then propagate and become areas of inherent weakness in the porcelain body during dynamic mechanical loading or even under constant change in ambient service temperatures. The larger these quartz crystallites, the more they are at risk of cracking and the sooner the insulator becomes at risk of failing. Indeed, research has demonstrated that punctured porcelain insulators typically have some or all of the following micro-defects.
