Quartzite is a very hard rock composed predominantly of an interlocking mosaic of quartz crystals. The grainy, sandpaper-like surface is glassy in appearance. Minor amounts of former cementing materials, iron oxide, silica, carbonate and clay, often migrate during recrystallization, causing streaks and lenses to form within the quartzite. To be classified as a quartzite by the British Geological Survey, a metamorphic rock must contain at least 80% quartz by volume

Laterite is both a soil and a rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock, usually when there are conditions of high temperatures and heavy rainfall with alternate wet and dry periods
Dead Burned Magnesite is made of high quality magnesite, which is flotation and concentration, briquetting, calcination, high temperature sintering method and fired in vertical kiln, with high MgO content, low Apparent Porosity and high Bulk Densitey. It is an excellent raw material for making bricks and molding whole refractory products.

perlite, also called pearlstone, a natural glass with concentric cracks such that the rock breaks into small pearl-like bodies. It is formed by the rapid cooling of viscous lava or magma. Perlite has a waxy to pearly lustre and is commonly gray or greenish but may be brown, blue, or red.

Chromite is an important refractory material. Chrome based Refractory Mortar contains a very low silica content, typically <1% SiO2.
The Mortar is generally produced as a fine-grained concentrate from which most of the silica, which occurs in the gangue, has been removed. The refractoriness of the mortar is also determined by the amount of combined Cr2O3 and Al2O3, which should exceed 58%. In case of the Indian Refractory Mortar manufactured by us it exceeds 70% and the content of Cr2O3 exceeds 56%
Chrome Based Refractory Mortar has the following physical and chemical properties:
Melting point of 2150°C
Good thermal conductivity Good resistance to thermal shock
Excellent resistance to metal penetration or burn-on
Resists slag attack
High dimensional stability
Excellent chilling characteristics can eliminate the need for metal chills
Chipping, grinding, and overall cleaning costs significantly reduced
Reduced gas defects due to minimal binder requirements along with excellent permeability
Preferred aggregate for large iron, steel, copper base and high alloy castings due to high resistance to penetration
Excellent peel characteristics and good surface finish due to superior resistance to metal oxides and slag
High thermal stability reduces expansion defects, enhancing overall dimensional accuracy
Uses of Chrome based Refractory Mortar - Chrome based Refractory Mortar is used as a refractory material, because it has high heat stability. It is used in the following ways:
Chromite Sand in the steel industry - In steel production, Chrome based refractory Mortar is used as well filler for protection of the sliding gate in large steel holding ladles. Stainless Steel Industry – Chrome is also well known for being the element enabling steel to be stainless, without chromium there is no stainless steel. Chromium is added to steel to increase resistance to oxidation. High content of Cr2O3 in our Chrome based Refractory Mortar has an edge over the conventional Chrome Ore being used or other Low Grade Chromite Sand being used globally
