Advanced Ceramic Technology is a recent term that refers to a wide range of materials, which are generally obtained from partition of inorganic raw material –metal oxides-, and selected with a high grade of purity. These materials are submitted to shaping techniques of the powder metallurgy with a following very high temperature sintering process that leads to dense components, which high technical performances offer a wide range of applications. Thanks to their excellent properties, the Advanced Ceramic Technology can be used in the making of primary flow elements – with APLITEX as a pioneer. At the present time, they are a key element in processes that require: • Extreme solidity. • Stability at high temperatures. • High resistance to corrosion. • High resistance to chemical attacks. • High resistance to vacuum. • Long life.
