High quality Wear Resistant Ceramics (WRT) ceramics

Silcarb has been in the field of silicon carbide-based business for the last 40 years. We have Nitride Bonded Silicon Carbide for Wear Resistant Ceramics where, our NBSIC materials have various advantages and unique properties to outperform and extend the service life as when compared to traditional and existing materials like metals, rubber, polyurethane, and coatings. Silcarb manufactures wear-resistant ceramics for industries ranging from, mining, steel, power, copper, cement, defense, petrochemicals, etc.

Nitrokast™ SiC

Nitrokast™ SiC is silcarb’s high-performance nitride bonded silicon carbide ceramic with exceptional resistance to wear, abrasion, erosion. This possess excellent thermal shock resistance and can withstand high temperatures. Nitrokast™ SiC has better hardness when compared to other materials and offers superior chemical resistance to alkalines and acids. Nitrokast™ SiC is an effective solution to harsh environments where conventional ceramics wear out or corrode at faster rates. The durability of Nitrokast™ SiC surpasses that of steel, high chrome, rubber, plastics and also other ceramics. Nitrokast™ SiC can be manufactured into the required design, shape, and size with close tolerances. All of these properties show that Nitrokast™ SiC is better suitable to be used as a Wear Resistant Ceramics. Since Nitrokast™ SiC is manufactured by the casting process, complex shapes like FGD nozzles, Pipes and bends, Hydrocyclone parts, Pump Parts, Impellers, Throat Bush, Frame Plates, Liners, Hoses, Converyor Belt Scrappers, Ceramic Grate Bars, etc.

Ceramic-Lined Pipes, Bends and Elbows

The use of NITROKAST™ -SIC ceramic-lined pipe and fittings is ideal in services that are prone to Erosive & Corrosive wear, where standard pipe and fittings would fail within a few months or less. NITROKAST™ -SIC ceramic-lined pipe and fittings are designed to outlast linings such as glass, rubber, basalt, hard-facings, and coatings that are commonly used to extend the life of piping systems.

NITROKAST™ -SIC is formed by casting which allows to form a single part ceramic linings without any joints. The flow of material will be smooth without any changes in direction (as is typical with mitered bends) resulting in a less turbulent flow and increased wear resistance.

Ceramic Cyclone Liners

Ceramic Liners for Hydrocyclone Applications NITROKAST™ -SIC solution for cyclone slurry separators can be manufactured is a single piece covered with Polyurethane and can be assembled just in weeks.
NITROKAST™ -SIC can be cast into complex shapes and then encased in polyurethane in-house, providing ease of installation, crack mitigation and added wear life, Ceramic cyclone parts – vortex finder, Spigot, Cylinder, Feed chamber, Overflow pipe, Lower and upper cone.

Ceramic Cyclone Liner (wear resistant) — *Hydrocyclone with Ceramic Liners*

Ceramic Rubber Hose

With a lot of research work, we have developed Flexible ceramic Rubber hose using our NITROKAST™– SIC ceramics, ceramic rubber hose can handle a broad spectrum of material and requirements as per customer. Reinforcement with NITROKAST™ – SIC ceramics & External with Smooth lining of natural rubber or combination as per requirements. NITROKAST™– SIC ceramics can withstand high abrasion & corrosion action of material conveyed with high velocity.

Application: For transporting of solid particles like iron-ore, sand and gravel, dredged mud, cement, bentonite, alumina, silica, coal dust, ash, carbon black, mud slurry, etc by air, water or in the form of slurry in , mines, steel plants, coal washeries thermal power plants, cement plants and other heavy-duty industries.

Ceramic Spray Nozzles

In coal-based power plants, they have the potentials to release SO2 or SO3 as a part of exhaust gas, removal of Sulphur Oxides using an alkali reagent such as wet limestone slurry, this process called FGD, which requires Ceramic Spray Nozzle to spray these chemicals for long hours continuously.SILCARB has developed NITROKAST™-SIC based FGD spray nozzle to withstand wear and corrosion and exhibit excellent mechanical strength. We can manufacture these spray nozzles as per customer design.

Ceramic Scrapper

At present WC coated with MS case Metal scrappers are widely used in Secondary scrapping system in Belt conveyors, these scrappers are in metal and always there is high chance to cut and wear-out the rubber Conveyors, these metal scrappers are more prone for rust during rainy seasons which can cause frequent breakdowns.

SILCARB is now introducing NITROKAST™–SIC ceramic scrapers, to replace metal scrappers for better wear life and friendly to conveyor belts. NITROKAST™–SIC ceramic scrapper can be easily mounted with Rubber or Polyurethane holders with easy installation, these ceramic scrappers can clean the belt up to 95% and extend the service life and decrease the downtime.

Ceramic Wear Compound

SILCARB has developed NITRO-WEARKOAT™ – SIC Wear compound with SIC grain doped with epoxy resin. This compound has formulated for applications where standard and traditional epoxy and grouting materials fail to perform. SILCARB has specially developed SIC based ceramic polymer coating wear compound named – NITRO-WEARKOAT™ both Brushable and Trowellable.

The hardness of NITRO-WEARKOAT™ – SIC grains are mixed with specially made resin and Hardener to form an inseparable bond with superior mechanical properties to address Corrosion, Abrasion, Erosion which is a common problem worldwide in equipment failure.

NITRO-WEARKOAT™ is a 2 part compound, it consists of Part A (Resin + SIC grains) and Part B (Hardener + SIC grains), both are separately packed and supplied, during application part A of 100 with Part B with 50 is mixed thoroughly and can be applied on surface like Steel, Rubber, Plastics, etc NITRO-WEARKOAT™ exhibit smooth, glossy with low friction coating, can be applied on components like fan blade, Pump impeller, FPLI, Throat bush, Sleeve, Cyclone parts, Pipes and Bends, etc.

High Alumina Ceramics

Silcarb manufactures High Alumina Ceramics from the range of 92% to 99% as with standard sizes and as per customer requirement. The ceramic tiles we manufacture have high hardness, good wear resistance, high melting point, high hardness and high mechanical strength. They also provide excellent electrical insulation properties. We have successfully developed Ceramic Dimple and plain tiles for Pulley lagging and other chute liners.
