It is used in making small images, ornaments and carvings. It is also used in high-pressure experiments. It has great thermal stability.
The average cost of nepheline syenite per ton is $60.00-70.00. It is an intrusive igneous rock that consists mainly of feldspar and nephelline. It is medium-to coarse grained in texture and are pale colored, pink or grey in color. It is used in the production of ceramic and glass products. It is silica free and an effective alkaline, thus it is preferred over feldspar in coatings. It is rich in alkalis and alumina. It occurs extensively on every major landmass.
The average cost of mullite per ton is $150.00-200.00. Its chemical formula is Al6Si2O13. It is a silicate mineral of post-clay genesis and is also known as porcelainite. It occurs in volcanic rocks. It is found in the form of needles in porcelain. It is used as a refractory in glass and steel industries as it has a high melting point. It is artificially produced during various melting and firing processes. It is also used in the ceramic industry in manufacturing kiln furniture items. It is a vital ingredient in making high strength infrared transmitting windows.
The average cost of magnesium sulfate per ton is $600.00-650.00. Its chemical formula is MgSO4. It is a chemical compound containing magnesium, sulfur and oxygen. It is the primary substance that causes the absorption of sound in seawater. It is used as a drying agent. In gardening, it is applied to potted plants, such as roses, tomatoes, potatoes as it has the ability to correct the magnesium deficiency in soil. It treats eclampsia in pregnant women. Its paste is used as an agent for dehydrating boils and carbuncles.
The average cost of magnesia per ton is $2450.00-2550.00. Its chemical formula is MgO. It occurs naturally as periclase and is a source of magnesium. It possesses high melting point and is thus used as a refractory material. It is an essential ingredient for making cement in dry process plants. Books are preserved in libraries using magnesia as it efficiently absorbs moisture. It is used for relief of heartburn and sore stomach, to improve indigestion, and as an antacid. It has side effects like nausea and cramping. It is also used as a protective coating in plasma displays.
The average cost of lithium carbonate per ton is $1500.00-4500.00. Its chemical formula is Li2CO3. It is a chemical compound of lithium, carbon and oxygen. It is used as a mood stabilizer in psychiatric treatment of manic states and bipolar disorder. It is a vital industrial chemical as it forms low-melting fluxes with silica and other materials and is used to strengthen glass and ceramic products. It is an important ingredient in both low-fire and high-fire ceramic glaze. It is found in fireworks as it imparts red flames.
The average cost of leucoxene is $150.00-300.00 per ton. It is a fine, granular alteration product of titanium minerals consisting mainly of rutile or anatase. It is formed through extensive weathering of ilmenite and possesses higher titanium dioxide content. It is used in welding electrodes. It varies in color from yellow to brown. It is found in some igneous rocks and iron ore deposits. It occurs extensively in countries like Australia, South Africa and USA.
