Feldspar is an amalgamation of a group of minerals containing potassium, sodium, calcium and aluminium silicates. They are the most common rock-forming minerals. general feldspar formulae: -------------------------- the common feldspar is potassium feldspar, namely, orthoclase (k2o, al2o3, 6sio2). Sodium feldspar is albite (na2o, al2o3, 6sio2) calcium feldspar is anorthite (cao, al2o3, 2sio2). applications of feldspar: ------------------------- feldspar is used as bonding agent along with magnesium oxide, magnesium chloride and other synthetic glue in the manufacture of abrasives, wheels, discs and other shapes. The three major areas of usages are: 1.in making the body composition of several types of procelain, china and earthenware and also in the preparation of glazes and enamel. 2.as an important ingredient in the glass sand batch. 3.as a bonding agent in the manufacture of bonded abrasives like wheels and discs of garnet, corundum, emery etc. the glass and ceramic industries are the major users of feldspar and account for 95% of their total consumption. the main vitrifying (fluxing) agent in ceramic bodies is feldspar. The majority of white ware bodies contain good proportions of feldspar which acts as a flux. In the ceramic industry, the flux is defined as that portion of the body which develops glass phase. This is provided mostly by feldspar. In order to develop the desired amount of vitrification, the amount of flux in a ceramic body should be in a correct , and if excess of flux is added, the fired body becomes very glassy and consequently, brittle. Feldspar is used in varying proportions in porcelain, china and earthenware. potash feldspar is used in varying proportions in the glass industry also. It may contain 10 to 15% of the batch. In the glass industry, feldspar is valued for two purposes, since it acts as a flux and secondly, for alumina content. Alumina provides the resistance in glass to impact, bendings, and thermal shock. feldspar is also used as bonding agent along with magnesium oxide, magnesium chloride and other synthetic glue in the manufacture of abrasives, wheels, discs and other shapes.

Benefits Vermiculite provides ammonium, potassium, calcium and magnesium to the growing plant due to the presence of cat ion exchange properties Promotes faster root growth, and gives quick anchorage to young roots Easily mixes with soil, peat, composted pine bark and other composted organic materials and fertilizers The Commercial uses of Vermiculite The majority of applications call for vermiculite in its exfoliated form. Vermiculite is a very versatile mineral because of its thermal stability and inertness. It is clean to handle, odorless, mold-resistant and also sterile due to the high temperature to which it is subjected in production. Vermiculite is used in the following segments of industries: Agricultural Animal Feed Anti-Caking Material Bulking Agent Fertilizer Carrier Pesticide Carrier Seed Encapsulant Soil Conditioner Construction Acoustic Finishes Air Setting Binder Construction Board Passive Fire Protection Floor & Roof Screeds Insulating and Light-Weight Concrete Gypsum Plasterboard Loosefill Loft Insulation Sound Deadening Compounds Horticultural Blocking Mixes Hydroponics Micro-Propagation Potting Mixes Root Cuttings Seed Germination Seedling Wedge mix Sowing Composts Twin Scaling Bulbs Industrial Absorbent Packing for Hazardous Goods Brake Pads & Brake Shoes Castables Dispersions Drilling Muds Filtration Fireproof Safes Fixation of Hazardous Material Furnaces Insulation Blocks & Shapes Insulation - High & Low Temperature Molten Metal Insulation Moulded Products Nuclear Waste Disposal Paints Perfume Absorbent Sealants

Vermiculite is a natural mineral that expands with the application of heat. The expansion process is called exfoliation and it is routinely accomplished in purpose-designed commercial furnaces. Vermiculite is formed by weathering or hydrothermal alteration of biotite or phlogopite.its name is from latin vermiculare, to breed worms, for the manner in which it exfoliates when heated. It typically occurs as an alteration product at the contact between felsic and mafic or ultramafic rocks such as pyroxenites and dunites. It also occurs in carbonatites and metamorphosed magnesium rich limestone. general vermiculie formulae: ---------------------------- 1. (na0.21, k0.39, mg0.19, ca0.13m, 6h2o) 2.
