ZRCI's RSLE family of Silica Composites are ultra thermal shock resistant, not brittle and fully machinable to tight tolerances. 


RSLE-57 is an integral part of the production of hot pressed diamond segments. RSLE-57 is used as a separator to electrically and thermally insulate a metal ram from a graphite pack. It will see in excess of 1800F with several thousands pound per square inch compression without any surface deformation.

Ideal for use in Dr. Fritch and ROBOSINTRIS diamond segment sintering machines.

ZRCI Refractory Sheet Type RSLE-57  

ZRCI Refractory Sheet Type RSLE-57 is a low expansion, high strength reinforced silica matrix composite. Designed for use as a high strength insulator in induction hot press applications, it is ideal for any application, which require a material with superior hot strength at temperatures as high as 1200C (2192F). 

RSLE-57's very low thermal expansion coefficient and high density combine to give it thermal shock resistance and durability not found in other structural ceramic composite materials. These properties give it much greater life in most hot pressing and induction heating applications. This thermal stability also helps to increase the life of your high prices graphite.

RSLE-57 is an integral part of the production of hot pressed diamond segments. It is used as a separator to electrically and thermally insulate a metal ram from a graphite pack. It will see in excess of 1000C (1832F) with several thousands pound per square inch compression without any surface deformation.

RSLE-57 will last many times longer than any calcium silicate, asbestos or other hot press insulation, as well as produce a better segment. This will save you time, money, and leave you with less waste material to dispose of.

The majority of diamond segment manufactures in the US and Europe has started using our material. They have stated that it will last 10 to 20 times longer in their most demanding hot press/sintering applications.

RSLE-57 was melted using an Oxy-Acetylene torch. The material melted without any thermal shocking or cracking. The material 1/2" away from the melt retains its full strength.

RSLE-57 exhibits exceptional non-wetting properties when used in contact with molten aluminum, zinc, lead, tin and other non-ferrous metals, making it useful in numerous casting, conveying, containing and forming applications. RSLE-57 is the ideal material for use as Dams, Spouts, Floats, Launders, Head Boxes, Baffles, Headers, Tips, Rings, Distribution Boxes, Stoppers, Basins, Snouts, Transition & Orifice Plates and Hot Top & Ingot Mold Liners. RSLE-57 is 100% organic free and contains no refractory ceramic fibers, (RCF's).


RSLE-57 can be machined to tight tolerances with conventional tooling

ZRCI Refractory Sheet Type RSLE-56 Moldable is a high silica fiber reinforced ceramic composite material that is easily cut and formed into flat sheets in addition to a wide variety of simple and complex shapes. When dried RSLE-56 Moldable becomes a hard rigid structure. Further heat treatment or exposure to process temperatures significantly increases the physical strength of this material.

Engineered and produced with low thermal expansion raw materials RSLE-56 exhibits greater thermal shock resistance than moldable alumina matrix composites. RSLE-56's binder is locked in place and will not separate from its supporting fiber reinforcement resulting in an homogeneous structure throughout the material. RSLE-56 is 100% inorganic and once dried undergoes little or no outgassing.


RSLE-56 Moldable makes relining troughs and casting tables easy. It can be backed up with low mass blanket, fiber board or calcium silicate to reduce the overall thickness and increase insulation value

ZRCI Refractory Sheet Type RSLE-501 is a low expansion high strength reinforced silica matrix composites in a cylindrical form. This remarkable material was designed for use as a high strength, durable insulator in induction heat treating applications. RSLE-501's very low thermal expansion coefficient and high hot strength combine to give it thermal shock resistance not found in other structural ceramic materials.

RSLE-501 is 100% organic free and contains no refractory ceramic fiber. It is readily machined to precision tolerances with conventional tooling. 


RSLE-501 Cylinders can be made as small as 1/2" ID up to 72" long and as large as 48" OD
