Phosphate Bonded Castable Refractory
Phosphate Bonded Castable Refractory (PBCR) is a type of refractory material that consists of a siliceous aggregate, phosphoric acid and special additives formulated to provide excellent properties for ceramic non-metal refractory applications.
PBCRs are commonly used in applications such as furnace linings and industrial ovens due to their high heat resistance, strength and chemical stability. They are also often chosen when it comes to refractory materials due to their cost-effectiveness, extensive range of available formulations, ease of use and easy application process.
PBCRs are composed of several components, including the siliceous aggregate, which is usually a combination of alumina and silica. The siliceous aggregate is combined with phosphoric acid to create the final material. Additionally, a range of special additives may be added in order to help meet the desired temperature and chemical stability requirements that the PBCR must have in order to function correctly in its intended application. These additives may include but are not limited to alumina, calcium carbonate or magnesium oxide.
In order to cast the PBCR, the siliceous aggregate, phosphoric acid and additives are mixed together and then poured into the desired medium. The PBCR may then be allowed to dry or it can be fired at a high temperature in order to achieve the desired thermal and chemical stability requirements.
PBCRs offer several advantages that make them ideal for applications that require high temperature and/or high chemical resistance. They are also cost-effective, insulating and non-porous, therefore making them suitable for a range of different industrial, commercial and domestic applications.
The combination of siliceous aggregate, phosphoric acid and special additives makes PBCRs a versatile and hard-wearing refractory material and one which offers a wide range of applications. PBCRs can be used in both dry and wet foam applications and they can even be used as a coating or a casting mould material.
PBCRs are also easy to use and install and as a result, they are gaining popularity within many industries. Additionally, PBCRs are becoming popular for a variety of residential uses, including outdoor fire pits and fireplaces.
In conclusion, PBCRs offer a range of advantages that make them one of the most popular types of refractory materials. PBCRs are cost-effective, easy to use, long-lasting and can be used in a variety of applications. As a result, these refractory materials have become a crucial part of many industries, commercial enterprises and homes and are the preferred choice for a number of applications.
