China, this word not only represents China, but also represents porcelain. China is a big country of porcelain. In ancient times, porcelain was already well-known. Among them, porcelain is a very important material - glazes, glazes, which make porcelain rich and colorful, and it is loved by people of all countries. Glaze is actually made of feldspar. A small piece of stone can be transformed into something magical. The albite is the most common kind of feldspar. The albite is generally a glassy crystal, and its role is also relatively large. Glass and ceramics are made using albite. Now sales of sodium feldspar are relatively good. Since it is so important, people can't wait to ask: How much is albite ? Do not worry, here we come together to understand how much money and a ton of sodium feldspar and other related knowledge, I hope to help you!

What is albite

Albite (NaAlSi3O8), also known as labradorite or glaucophane, is a triclinic system with a specific gravity of 2.6 - 2.65 g/cm3. It is grayish yellow with a theoretical composition of SiO268.8%, Al2O319.4%, and Na2O11. .8%. The albite is a good raw material of ceramic flux (it plays the role of fluxing). It has the advantages of saving fuel consumption, improving the mechanical strength of the green body, and reducing the water absorption rate. It is mainly used in ceramics, glass, porcelain enamel and other departments.

Albite is a sodium aluminosilicate (NaAlSi3O8), a triclinic glassy crystal, generally colorless, white, yellow, red, or black, and is a type of feldspar. The albite is a platy silicate structure with a specific gravity of 2.62, a Mohs hardness of 6-6.5, and an anorthite content of less than 10%.

Albite is a sodium mineral in the plagioclase solid solution series. It is most common in pegmatites and granites. It was first discovered in Sweden in 1815.

Characteristics of albite

Albite has the following characteristics:

1. The melting of quartz, clay and mullite at high temperature is rapid and the solubility is high.

2, low melting temperature, good transparency.

3. The melting temperature range is narrower than that of potassium feldspar, and the melt has a low temperature viscosity and changes rapidly with temperature.

  

Albite effect

1. Before firing, albite is a very plastic raw material. In addition, it can also shorten the drying time. In addition, albite can also be deformed. In general, it is relatively easy to use, as long as we make good use of it, we can let it play its biggest role.

2. The middle of the albite contains substances that can help us lower the firing temperature, so it is more appropriate when firing.

3. If sodium feldspar is to be made into glass, it is melted at high temperatures. Between the melted particles, the albite is capable of melting other substances. These include kaolinite and quartz lamps. This also improves the mechanical strength of the product.

4. The effect of sodium feldspar after firing is relatively large. At the same time, if it is made, it can improve translucency. However, the firing temperature is not the same as other materials.

5. We also have requirements for albite when firing ceramics. We need to make a selection. If it is not flawless, it can be made into a better ceramic.

Albite use

In addition to industrial raw materials, albite minerals account for more than 30% of the ceramic industry, and are widely used in chemical and other industries.

1, glass solvent: feldspar is one of the main components of the glass mixture, feldspar with high alumina, low iron content, can reduce the amount of alkali. In addition, the feldspar melted into a glass and the process is relatively slow, and the crystallization ability is small. It can prevent crystals from being precipitated during glass formation and destroy the product. The feldspar can also be used to adjust the viscosity of the glass. In general, various glass mixtures use potassium feldspar. Or albite.

2. Ingredients for ceramic bodies: Before firing, feldspar can act as an inert raw material, reduce the drying shrinkage and deformation of the body, improve the drying performance, shorten the drying time, and can be filled as a flux in the body during firing. The compacting of the green body reduces voids and improves the light transmittance of the green body.

3, ceramic glaze: make the glaze soft, reducing the melting temperature of the glaze.

4. Enamel raw materials: Mainly feldspar and other mineral raw materials are blended into yttrium, and the blending amount is usually 20-30%.

5. Others: Potassium and albite can also be used as high-quality raw materials for fertilizer production.

  

How much is albite

The price of a ton of albite ranges from a few hundred dollars. It is suggested that before buying, you may wish to visit the store first. Shop around, depending on your actual situation.

Note: This price is for reference only! Due to geographical differences, of course, the price will be different. For more details on the prices, please refer to the local distributors!

Albite instructions for use

Albite is generally suitable for low temperature ceramics:

1, before firing, feldspar and quartz are non-plastic materials, can shorten the drying time of the body, reduce drying shrinkage and deformation.

2, feldspar is the main flux raw material in the blank glaze, such as feldspathic porcelain, feldspar in the body accounts for about 25%, accounting for about 50% in the glaze, the main role is to reduce the temperature of the blank glaze firing.

3. Feldspar melts at a high temperature and grows into a stone glass filled in between the particles of the green body, and can dissolve other minerals such as kaolinite, quartz, etc. to make the body compact, which helps to improve the mechanical strength and electrical properties of the product. And translucency.

4. Compared with K-feldspar, albite has a greater effect on lowering the firing temperature of the blank glaze, and at the same time it can improve the semi-transparency of the product, but the firing temperature range is not as wide as the potassium feldspar.

5. Requirements for feldspar in ceramic production:

a. The contents of K2O and Na2O are as high as possible, and the contents of colored oxides Fe2O3 and TiO2 are as low as possible;

b, SiO2 content should be 63% -68%, Ali2O3 content should be in the range of 17% -23%;

c. The content of CaO in feldspar should not be too high. If the content is too high, it can be easily used to reduce the sintering temperature of the billet, and the glaze can affect the flowability of the glaze.

Editor's summary: At present, China's feldspar mineral products have not yet formulated a uniform product quality standard. The industrial application department mainly requires feldspar products with low iron content. After reading the above introduction, will everyone lament that soda feldspar had so many uses?
