Background

Ceramics are a generic term for ceramics and porcelain. The pottery was invented in the neolithic age about 8000 years ago. Common ceramic materials are clay, alumina, kaolin, and the like. Ceramic materials generally have a high hardness but a poor plasticity. Besides being used for tableware and decoration, ceramics play an important role in the development of science and technology. The ceramic raw material is extracted from a large amount of clay which is the original resource of the earth. The clay has toughness, can be plasticized when meeting water at normal temperature, can be carved in a micro-dry way and can be ground in a full-dry way, can be made into pottery to contain water when being burnt to 700 ℃, and can be vitrified when being burnt to 1230 ℃, almost does not absorb water, and is high-temperature resistant and corrosion resistant. The flexibility of its usage has various creative applications in today's cultural science and technology. A pottery is invented. The ceramic materials are mostly oxides, nitrides, borides, carbides, and the like. The glaze is a vitreous thin layer covered on the surface of ceramics and enamel. For example, the colored glaze and the tri-colored glaze of the Tang Dynasty, which are popular in the Tang Dynasty, are prepared by coating white, green, brown and blue glaze on a biscuit, baking at a kiln temperature of 800 ℃, are mostly used as a cosmesis, coloring the glaze, painting on a baked biscuit, baking at a low temperature, and painting on a blank in the Song Dynasty at the earliest because the color is attached to the glaze, painting under the glaze on the blank, then glazing and baking at a high temperature, wherein colored patterns are never peeled off under the glaze, and the colored patterns are firstly found in the Tang Dynasty, red glaze, copper oxide as a coloring agent, painting on a blank, baking red flowers at a high temperature after glazing, starting from the Yuan Jingdezhen, glaze products used by most of the current pottery enterprises can be roughly classified into 1, lead glaze and lead-free glaze, 2, raw glaze and fritted glaze, 3, primary firing or secondary firing, 4, ceramic tiles, tableware, sanitary ceramics and electric porcelain glaze, 5, and 6, dip glaze, spray glaze, 6, and spray glaze which are divided by the glazing method, High-temperature glaze and low-temperature glaze, 7 high-expansion glaze and low-expansion glaze, 8 firing atmosphere oxidizing flame, neutral flame and reducing flame, 9 colored glaze and colorless glaze, 10 transparent glaze and opaque glaze, 11 glossy glaze, dull glaze, semi-dull glaze or patterned glaze and the like. At present, the cost of the ceramic glaze is higher, the manufacturing method is more complex, the glaze is easy to peel off, and the color is not bright enough.

Limestone is the main component of calcium carbonate (CaCO 3). Lime and limestone are a large number of raw materials used in construction materials, industry. Limestone can be directly processed into stone and burnt into quicklime. The quicklime CaO absorbs moisture or is added with water to form hydrated lime, the main component of the hydrated lime is Ca (OH)2 which can be called as calcium hydroxide, and the hydrated lime is blended into lime slurry, lime paste and the like which are used as coating materials and tile adhesives.

Quartz, a geological term commonly referred to as low temperature quartz (α -quartz), is the most widely distributed one of the minerals in the quartz family. The quartz in a broad sense also includes high temperature quartz (β -quartz), chrysolite, and the like. The main component is SiO2, which is colorless and transparent, often contains a small amount of impurity components, and becomes translucent or opaque crystals with hard texture. Quartz is a mineral resource with stable physical and chemical properties, and the crystal belongs to oxide minerals of trigonal systems. The quartz block is also called silica, and is mainly used as raw material for producing quartz sand (also called silica sand), as well as quartz refractory material and raw material for firing ferrosilicon.

Calcite is a calcium carbonate mineral, which is the most common of natural calcium carbonates. Calcite is therefore a widely distributed mineral. Calcite has various crystal shapes, and the aggregate thereof may be a cluster of crystals, and may be granular, massive, fibrous, milky, earthy, or the like. Knocking calcite can produce many square fragments, so the name is calcite.

Barium carbonate (Barium carbonate), molecular formula BaCO3, molecular weight 197.34. Inorganic compounds, white powders, are poorly soluble in water and readily soluble in strong acids. Toxic and has wide application. The carbonization method comprises the steps of introducing ^ carbon dioxide gas into a barium sulfide solution (see barium sulfide for preparation) for carbonization to obtain barium carbonate slurry, and carrying out desulfurization washing, vacuum filtration, drying at 300 ℃ and crushing to obtain a finished barium carbonate product. The reaction formula is as follows: BaS + CO2+ H2O → BaCO₃And the complex decomposition method of ↓ + H2S ↓ is to carry out the double decomposition reaction of barium sulfide and ammonium carbonate, and then the bismuth carbonate finished product is obtained after washing, filtering, drying and the like. The reaction formula is as follows: BaS + (NH4)2CO3 → BaCO₃The method for converting the witherite into the barium carbonate comprises the steps of reacting witherite ore powder with ammonium salt to generate soluble barium salt, recycling ammonium carbonate, adding the ammonium carbonate into the soluble barium salt to precipitate refined barium carbonate, filtering and drying to obtain a finished barium carbonate product. The obtained mother liquor is recycled.

Borax, generally written as Na2B4O7 · 10H2O, is a very important boron-containing mineral and boron compound. Usually a white powder containing colorless crystals, readily soluble in water. Borax has a wide range of applications, and can be used as a cleaning agent, a cosmetic, an insecticide, and also can be used for preparing a buffer solution and preparing other boron compounds, etc. Commercial borax tends to have been partially weathered. Borax has high toxicity, and is mostly forbidden as a food additive in various countries in the world. Excessive intake of boron in the human body causes cumulative toxicosis in multiple organs.
