MH Group supplies soda feldspar to ceramic and glass manufacturers. Soda feldspar, also called sodium feldspar, is the main flux in vitrified tiles, sanitaryware and many glazes. In the kiln it melts before the other materials and pulls them into a dense, strong body.
Factories buy it from us for their own production, traders buy it wholesale, and overseas buyers order it for export from Karachi. Feldspar in Pakistan is sold in many grades, and the right one depends on its sodium, potassium and iron content. It is one of the ceramic and glass minerals we supply.
Soda feldspar is a feldspar rich in sodium and made mostly of the mineral albite. Albite sits at the sodium end of both main feldspar groups, the alkali feldspars and the plagioclase feldspars. Good ceramic grades are white or off-white with low iron, so they do not stain the fired body.
Compared with potash feldspar, soda feldspar melts at a lower temperature and forms a more fluid melt. Fast-fired floor and wall tiles and glossy glazes benefit from this. Potash feldspar melts over a wider range and keeps the body stiffer, so porcelain and some sanitaryware bodies blend the two. Sodium also raises thermal expansion, so a glaze heavy in soda feldspar can craze unless the recipe is balanced.
Soda feldspar fluxes the body so tiles reach low water absorption and high strength within short firing cycles.
Washbasins and WCs need a dense body that does not soak up water, and feldspar forms the glassy phase that seals it.
Feldspar adds alkali and alumina to glaze recipes, helping the glaze melt smoothly and resist scratching.
Glass makers add feldspar as a source of alumina, which makes container and flat glass more durable, alongside silica sand for glass making and soda ash.
Fine-ground feldspar also works as a filler in paints, plastics and rubber.
Ask for the analysis before you compare offers, because a low rate means little if the grade does not suit your kiln.
Na2O and K2O figures show how strongly the feldspar will flux and whether it is a true soda grade.
Low Fe2O3 keeps tiles and glazes white. Darker grades can still suit colored bodies or bodies covered by a glaze.
Glazes need finer powder than tile bodies, and the share of free quartz changes the silica balance of your recipe.
The soda feldspar price depends on the grade, the iron content, lumps or powder, the mesh size, the quantity and the delivery point. The feldspar powder price is higher than the lump price, because grinding and bagging add cost. When you ask for a rate, share your target analysis, form and monthly tonnage.
Traders can buy soda feldspar wholesale for resale, and export buyers can order larger lots packed and loaded in Karachi.
We start from your body or glaze requirement, so the grade offered matches your kiln and not only a price.
Feldspar can be ordered with plastic clay for tile bodies, china clay and silica sand from one supplier.
MH Group serves plants inside Pakistan and buyers abroad, and its logistics division can arrange trucking and sea freight for the order.
Soda feldspar is also called sodium feldspar, and in mineral terms it is mostly albite, with the formula NaAlSi3O8. Traders sometimes write it as Na feldspar. Whatever the name on the offer, check the sodium oxide figure in the analysis to confirm it is a true soda grade.
Soda feldspar is rich in sodium and melts at a lower temperature into a more fluid glass. Potash feldspar is rich in potassium, melts over a wider range and stays stiffer, which helps pieces keep their shape in the kiln. Many tile and sanitaryware bodies use a blend of both.
The soda feldspar price in Pakistan changes with grade, iron content, mesh size, quantity, packing and delivery distance, so no single rate fits every buyer. Bulk tonnage lowers the feldspar price per ton. Request a soda feldspar quote with your analysis and monthly requirement.
Feldspar is used mainly as a flux in ceramic tiles, sanitaryware, tableware and glazes, and as a source of alumina and alkali in glass. Ground feldspar also works as a filler in paint, plastics and rubber. Soda grades suit fast firing and glossy glazes, while potash grades suit porcelain.
Yes, over geological time. When feldspar in granite weathers, water slowly breaks it down into kaolinite, the clay mineral in china clay powder (kaolin). Kaolin deposits often form where feldspar-rich rocks have been altered, which is one reason the two minerals are so closely linked in ceramics.
