Medical stone is a common mineral, its chemical formula is Mg2Al3(SiO4)3, which belongs to silicate mineral, and its hardness is 6-6.5. Its name comes from Greek, which means "corroded marble" because it can be corroded by acid. Medical stone is common in igneous rocks and metamorphic rocks, and can also be found in some sedimentary rocks. Its colors are white, gray, yellow, green and so on.

The use of medical stone

Medical stone has many uses in industry. It can be used to make building materials such as ceramics, glass, enamel, bricks, etc., and can also be used to make fertilizers, fertilizers and fertilizer additives. In addition, medical stone can also be used to make refractories, grinding materials and coatings.

Operation steps of medical stone

Taking the manufacture of ceramics as an example, the operation steps of medical stone are introduced below.

Step 1: Material selection

First of all, we should choose medical stone minerals suitable for ceramics. The color, hardness and purity of medical stone will affect the quality of ceramics.

Step 2: Grinding

Grinding medical stone minerals into powder can use equipment such as ball mill. This process is very important, because the fineness of powder will affect the density and strength of ceramics.

Step 3: Mix.

Mix medical stone powder with other raw materials, and add some additives as needed, such as clay, quartz, feldspar, gypsum, etc. In the process of mixing, it is necessary to control the samples and mixing time to ensure the quality of ceramics.

Step 4: Forming

Mixed materials can be formed by pressing, injection molding, extrusion and other methods. It is necessary to control the temperature, pressure and speed in the molding process to ensure the shape and size of ceramics.

Step 5: Fire.

The molded ceramics are put into a kiln for firing. Sintering temperature and time will affect the density and strength of ceramics. The fired ceramics can be surface treated and decorated.
