Home    About us    Company presentation
Years of experience in the production of aluminium oxides and decades of continuous development have made Silkem a widely recognised manufacturer of special materials in the fields of zeolites, silicates, special alumina and boehmites.

Silkem sells its products in more than 40 markets. The company’s strategic advantage and an important part of its development strategy are its flexibility and the dynamic ability to adapt in meeting quality and logistic needs of its customers. Close cooperation with customers and own development of new products enable a continuous expansion and specialisation of the production programme.

Company history

Silkem was founded in 1992 on the basis of 40 years of experience in the production of aluminium hydrates and other types of alumina in Kidričevo, Slovenia. After production in the red section of the old alumina plant was closed down, successful adaptations and an innovative approach allowed for the start of two basic production programmes: zeolites with silicates and special alumina.

Environmental requirements have allowed for a fast assertion of synthetic zeolites in the production of detergents. To adapt to new production methods (dry mixing) in the mid-1990s, Silkem also began with production of zeolites and silicates in granulated form with additional components of detergents. At the turn of the 21st century, the company developed the production of ultra pure zeolite, which resulted in new sales opportunities in plastic production. With development of granulation and calcination of zeolite powders, which was concluded in 2011, the company’s position in this market was further strengthened and new opportunities in other application fields emerged. In 2017 the production programme of granulates was expanded to dried silicates with high bulk density.

The development of special alumina was directed towards the use in refractory materials. In a short span of time, the company became an important supplier of highly calcined and fine ground alumina. So as to meet customer requirements, the first line for the production of tabular alumina was set up in 2003 and within a few years, capacities doubled. In 2007 the sales programme for the refractory industry was expanded with sintered spinels. Special methods in the preparation of raw materials and additional processing of the final products have allowed Silkem to expand the production programme to calcined and tabular alumina with special properties, enabling their use in other application fields. Changes in the MAL Group, the parent company of Silkem since 2001, have resulted in a new ownership structure after 2012. The ownership share in Silkem Hungary enabled Silkem to expand its range of products from the special alumina programme.

In 2015 production capacities and own development allowed for the start of the boehmite production programme.

Quality policy

The quality of the company’s products and services is dictated by industry standards and Silkem’s commitment to continuous development and improvements in this field.
