1. Alumina ceramic plate Introduction:

Innovacera develops and manufactures products made of technical ceramics for customer-specific applications. 
Starting with problem analysis and generation of ideas, Innovacera carries out projects in which cost-efficiency is of paramount importance. Innovacera produces prototypes, small and larger series of custom made products in-house.

High purity alumina ceramics are ideal for environments where resistance to wear and corrosive substances are required. Alumina ceramic has excellent thermal stability, which means that it is widely used in areas where resistance to high temperatures is essential.

Alumina ceramic is the material of choice for alumina wear parts. The proven wear and heat resistance of alumina wear parts makes them ideal for the manufacture of wear-resistant components.
