Overview of Refractories

COURSE NO: T05-003
Overview of Refractories
Course Highlights

This online engineering PDH course provides insight to the type of refractories, their properties and applications, and how they may be applied to give better fuel efficiency and service life.


Refractories are inorganic, nonmetallic heat resistant materials that can withstand extreme temperatures, and in many cases chemical attack, abrasion, thermal shock and rough handling. These are widely used in the lining of high temperature surfaces such as furnaces, kilns, reactors and other processing units in manufacturing, thermal, metallurgical and chemical equipments worldwide.


Refractory selection for a specific application is invariably built upon a combination of material qualities and its composition. Refractories are expensive, and any failure in the refractories can result in a great loss of production time, equipment, and sometimes the product itself. The various types of refractories also influence energy consumption and product quality; therefore, the problem of obtaining refractories best suited to each application is of supreme importance.


This 5 PDH online course is intended for mechanical, chemical & process engineers, working in chemical, thermal, metal & mining, manufacturing and engineering industries.
