Brazil occupies a prominent position in the worldwide floor and wall tiles. In order to serve the national market, as well as several countries in which it operates, Estiva focuses on the control of its raw materials and the final characteristics of its ceramic rollers and refractory pieces.

Aiming to supply a growing demand for lengthy rollers and high-temperature applications, Estiva joined forces with an Italian group, through a joint venture, to implement a new plant in Tunisia to meet these needs and also facilitate logistics for customers around the world.

Estiva Refratários is a leader in the supply of kiln furniture for sanitaryware market, maintaining frequent contact with customers to understand the new demands, be them for lighter refractory parts (aiming at fuel economy and faster cycles), tailored designs and delivery time that meet their expectations.

Such differentials are recognized by the major national groups, as well as by the largest sanitary manufacturers in the world, whether located in the American, European, Arabic world, African and Oceania continents.

For the sanitary ware market, Estiva, in addition to batts, supports, perimeter blocks, etc. also supplies materials from Schunk – Germany, such as silicon carbide bars and bore-gride batts.

Even with the strong presence of Chinese products in the domestic market, tableware segment is still very significant and challenging, since process characteristics require refractory products with low thermal mass, load stability and resistance to aggressive thermal shocks.

With specific mixes for this application, Estiva products have been used by several customers due to the performance under application, flexibility and short time of delivery and special care of our  team.

This is where technique joins art to create unique articles in the hands of our artists. Although it is a constantly growing market, it is also challenging because each “atelier” has a distinct feature and requires us to have tailored solutions.

As the production of artistic ceramics is quite peculiar and small, when compared to other ceramic markets, our products also meet these characteristics, satisfying the specific needs of each ceramist, whether by special pieces or even assisting in the correct application of refractory products.

Powder metallurgy is a metal forming process that has a wide range of applications, such as the manufacturing of parts for automotive applications, home appliances, cutting and power tools, braquets for dental appliances and others.

As one of the characteristics of these products is precisely dimensional tolerance and, in many cases, with direct application in the product of our customers. Estiva refractory solutions have the necessary stability to guarantee the accuracy of the metal parts produced.

Heat treatment is a heating and/or cooling process of materials aiming at obtain special characteristics and different from those initially presented, such as increase in hardness and mechanical strength, softening or reduction of stress level, among others.

In the case of heating and the use of heat treatment furnaces, Estiva has the capacity to supply refractory parts, such as batts, rollers, burners, radiant tubes and special parts, which meet the characteristics of these processes without compromising the final quality of the products to be thermally treated.

A peculiar characteristic in the production of insulators and electrical porcelain is the high density of load and extremely heavy parts, as example pieces for power transmission lines applications.

In addition to its products such as slabs, supports and kiln furnitures, Estiva has a partnership with Schunk – Germany for the supply of infiltrated silicon carbide beams, well known for its excellent mechanical strength and high durability even under high loads.

These types of furnaces (muffles) are widely used in laboratories, artistic ceramics, research centers and in special applications or equipment for heat treatment.

Our materials are used as firing support or protection and prevent contact between piece to be fired/treated and heating element itself, leading to its premature failure and damaging the equipment itself. Due to this, our materials are free from metallic contaminations, have dimensional stability and resistance to heating and cooling cycles.

Abrasives are natural or industrial products used to chop, cut or even polish some surface and, due to the need for hardness and stability, are mostly made by industrialized raw materials and burned in furnaces with high load density of charge.

For smaller size and lighter abrasive pieces, refractory products based on cordierite-mullite can be an excellent choice against other types of refractory, highlighting its performance and excellent cost-benefit ratio.

Although it seems somewhat strange, refractory parts are also used in furnaces for the manufacture of various foods, for example pizza ovens or those used for breads and suchlike.

Due to the low temperature of application and demand for thermal shock resistance due to the “open-and-close” ovens doors, Estiva cordierite products are widely used in these applications and having very good results.
