FELDSPAR
Binary Mineral Orthoclase (KAlSi3O8) and Albite (NaAlSi3O8)
High-quality mineral with variable sizes (0mm up to 5mm), Sodium-Potassium content up to 12%.
Feldspar is by far the most abundant group of minerals in the earth's crust, forming about 60% of terrestrial rocks. Most deposits offer sodium feldspar as well as potassium feldspar and mixed feldspars. Feldspars are primarily used in industrial applications for their alumina and alkali content. The term feldspar encompasses a whole range of materials. Most of the products we use on a daily basis are made with feldspar: glass for drinking, glass for protection, fiberglass for insulation, the floor tiles and shower basins in our bathrooms, and the tableware from which we eat. Feldspar is part of our daily life.
Basically, the two properties which make feldspars useful for downstream industries are their alkali and alumina content. On those elements, we can distinguish three families: Feldspathic sand, Pegmatite, and Feldspar. A further distinction can be made between sodium, potassium, and mixed feldspars, depending on the type of alkali they contain. Feldspars play an important role as fluxing agents in ceramics and glass applications, and also are used as functional fillers in the paint, plastic, rubber and adhesive industries.
Glass: Feldspar is an important ingredient in the manufacture of glass and an important raw material as well, because it acts as a fluxing agent, reducing the melting temperature of quartz and helping to control the viscosity of glass. The alkali content in feldspar acts as flux, lowering the glass batch melting temperature and thus reducing production costs.
Ceramics: In the manufacture of ceramics, feldspar is the second most important ingredient after clay. Feldspar does not have a strict melting point since it melts gradually over a range of temperatures. This greatly facilitates the melting of quartz and clays and, through appropriate mixing, allows modulations of this important step of ceramic making. Feldspars are used as fluxing agents to form a glassy phase at low temperatures and as a source of alkalies and alumina in glazes. They improve the strength, toughness, and durability of the ceramic body, and cement the crystalline phase of other ingredients, softening, melting and wetting other batch constituents.
Fillers: Feldspars also are used as fillers and extenders in applications such as paints, plastics, and rubber. Beneficial properties of feldspars include good dispersibility, high chemical inertness, stable pH, high resistance to abrasion, low viscosity at high filler loading, interesting refractive index, and resistance to the frosting. The products used in such applications are generally fine-milled grades.
Enamel frits and glazes: Feldspar assists the enamel composition, assuring the absence of defects and the neatness of the end product: e.g. enamel frits, ceramic glazes, ceramic tile glazes, sanitaryware, tableware, electrical porcelain, and giftware.
And many other end-uses: paint, mild abrasives, urethane, welding electrodes (production of steel), latex foam, the welding of rod coating, and road aggregate.
In the flooring sector, feldspar is the main constituent in the body composition. It is used as a flux, lowering the vitrifying temperature of a ceramic body during firing and forming a glassy phase. Surface tension pulls the remaining solid particles together, giving densification of the ceramic body. With rising temperatures, the alkalis become more active and first dissolve the clay particles and then the free silica.
In tableware, feldspar gives a good fusibility for a product without defects.
In sanitaryware, the use of feldspar within vitreous ceramic bodies is used to facilitate the optimization process.
KAOLIN
White to Yellowish Clay Kaolinite (Al2O3(SiO2)2(H2O)2)
High-quality mineral with variable sizes (Lumps), a high percentage of AL2O3, and less content of FE2O3.
Kaolin is a mixture consisting principally of the mineral kaolinite and containing varying amounts of other minerals such as muscovite, quartz, feldspar, and anatase. Also known as china clay, kaolin is a soft white clay that is an essential ingredient in the manufacture of china and porcelain and is widely used in the making of paper, rubber, paint, drying agents, and many other products. It has a role as an excipient and an antidiarrhoeal drug. It contains kaolinite.
The major domestic markets for kaolin were, in descending order of tonnage, paper coating and filler, refractory products, fiberglass, and mineral wool. paint, catalyst manufacture, rubber, and heavy-clay products. Other markets were ceramics, chemical manufacture and plastics
WHITE SILICA SAND
Silicon Dioxide, High Purity (SiO2) Silica Sand
Quartz Silica Sand 99% SIO2 with a very less FE2O3 content, multiple sizes from (0mm up to 5mm).
High purity sand, almost entirely composed of silica, is a major industrial commodity. Silica sand products are marketed in a wide range of grades, including extremely fine grades known as flours. Silica is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms. Silica is the most abundant mineral in the Earth's crust. Silica is manufactured in several forms including glass, crystal, gel, aerogel, fumed silica.
For industrial and manufacturing applications, deposits of silica yielding products of at least 95% SiO2 are preferred. Silica is hard, chemically inert and has a high melting point, attributable to the strength of the bonds between the atoms. These are prized qualities in applications like foundries and filtration systems. Quartz may be transparent to translucent and has a vitreous luster, hence its use in glassmaking and ceramics. Industrial sand’s strength, silicon dioxide contribution, and non-reactive properties make it an indispensable ingredient in the production of thousands of everyday products.
