Minerals We Supply to the Refractory Industry

$Best Chamotte (Refractory Clay) exporter from India - Shri Balaji Mines and Minerals$

Chamotte (Refractory Clay)

Chamotte - fired refractory clay - is the backbone raw material of the refractory industry. Produced by calcining raw clay at high temperatures, it becomes a stable ceramic material with high refractoriness and excellent thermal shock resistance. Its pre-fired nature eliminates shrinkage issues and contributes dimensional stability to formulations that raw clay additions cannot provide.

Used as the primary aggregate in fireclay refractory bricks, a critical grog addition in castables to control shrinkage and improve thermal shock resistance, the main body material in kiln furniture and kiln car structures, and a key component in refractory mortars for furnace lining installation and in-situ repair across steel, glass and ceramic industries.

We supply chamotte in multiple grades based on Al₂O₃ content - in lumps and granule form for refractory manufacturers globally.

Pyrophyllite

Pyrophyllite is one of the most technically valuable minerals in refractory manufacturing - uniquely characterised by its transformation to mullite at approximately 1200°C, imparting exceptional thermal shock resistance and high-temperature dimensional stability. This property makes pyrophyllite irreplaceable in premium refractory formulations and explains strong demand from buyers in China, Europe and South Korea.

Used in high-alumina refractory bricks, monolithic refractories for steel and blast furnace linings, castables for glass and cement kiln applications, and specialty refractory coatings where thermal cycling resistance under extreme heat is critical.

We supply pyrophyllite in refractory grade in lumps, chips, granules and powder - multiple grades based on Al₂O₃ content suited to different international refractory specifications.

Kaolin

Kaolin is an essential raw material in refractory manufacturing - providing alumina (Al₂O₃) and silica (SiO₂) to body formulations while contributing plasticity for forming and refractoriness for high-temperature performance. Both raw and calcined forms serve distinct roles - raw kaolin contributes plasticity and workability to castable mixes while calcined kaolin and meta kaolin provide highly reactive alumina-silica that improves fired density, strength and chemical resistance.

Used in fireclay refractory bricks, low-cement castables, refractory coatings, kiln furniture and specialty shapes for steel, glass and cement kiln applications by manufacturers across China, Italy, Germany and South Korea.

We supply kaolin in raw lumps, washed lumps, calcined powder and meta kaolin powder in multiple grades suited to refractory industry requirements globally.

Ball Clay

Ball clay serves as a plasticiser and binder in refractory castable, plastic and monolithic formulations - contributing workability, green strength and binding performance that allows mixes to be efficiently shaped, cast or rammed before firing. Its high plasticity index enables smooth forming of complex refractory shapes including arch bricks and kiln furniture where dimensional accuracy is critical.

High plastic ball clay is preferred in plastic refractory mixes and in-situ furnace repair compounds where maximum workability is required. Its controlled firing behaviour ensures minimal disruption to overall refractory chemistry at the low addition levels typically used by manufacturers globally.

We supply ball clay in lumps and chips across semi plastic, high plastic and blended grades - suited to castable and monolithic refractory formulations for manufacturers globally.

Bentonite

Bentonite is used as a binding agent in refractory castable and monolithic formulations - providing green strength during mixing, casting and curing before firing or heat-curing in service. Its swelling and bonding properties deliver effective performance at very low addition levels of 1 to 3% by weight - contributing significant binding strength without materially affecting fired refractory chemistry or high-temperature performance.

Sodium bentonite in powder form is the industry-standard refractory binding grade - its high swelling index, gel strength and compatibility with refractory systems ensure effective binding across low-cement, ultra-low-cement and no-cement castable formulations used by refractory manufacturers in China, Middle East and Southeast Asia.

We supply sodium bentonite in 200 mesh powder suited to refractory castable binding applications globally.

Quartz

High-purity quartz is used in silica-based refractory formulations - particularly silica bricks, refractory shapes and ramming mixes for glass furnaces, coke ovens and hot blast stoves where high SiO₂ content and thermal stability are primary performance parameters. Quartz promotes tridymite and cristobalite phase formation during high-temperature service - giving silica refractories their near-zero thermal expansion above 600°C.

Used in silica refractory brick formulations for glass melting furnaces, coke oven linings and hot blast stoves where consistent high-purity silica content is essential for refractory performance and longevity across thermal cycling.

We supply high-purity quartz in lumps, granules and powder - multiple grades suited to silica refractory applications for glass, steel and chemical industry manufacturers globally.

Quartzite

Quartzite is a dense, hard metamorphic rock composed of interlocking quartz crystals - offering superior mechanical strength, thermal stability and chemical resistance compared to standard quartz. These properties make it specifically valuable in refractory applications where high density, crush resistance and load-bearing stability at elevated temperatures are required.

Used as a high-density silica aggregate in silica refractory bricks for glass and coke oven linings, in ramming mixes for steel furnace and torpedo ladle linings, as a metallurgical refractory aggregate in blast furnace hearth applications, and in high-temperature kiln structures where superior mechanical strength is critical.

We supply quartzite in lumps, chips and granules — multiple grades suited to silica refractory, metallurgical and high-temperature refractory applications for manufacturers globally.
