Metal ytterbium block is a silver white soft metal with luster and easy oxidation. It slowly corrodes in the air and is soluble in dilute acids and liquid ammonia. It can slowly react with water, and divalent salts are green, soluble in water, and react with water to slowly release hydrogen gas; Trivalent salt is colorless. The oxide is white in color. Silver white metal with ductility, rich in luster.

Metallic ytterbium is silver gray, ductile, and has a soft texture. At room temperature, ytterbium can be slowly oxidized by air and water. Similar to samarium and europium, ytterbium belongs to the variable valence rare earth, and can also be in a positive divalent state in addition to being usually trivalent. Due to this variable valence characteristic, the preparation of metallic ytterbium should not be carried out by electrolysis, but by reduction distillation method for preparation and purification. Usually, lanthanum metal is used as a reducing agent for reduction distillation, utilizing the difference between the high vapor pressure of ytterbium metal and the low vapor pressure of lanthanum metal. Alternatively, thulium, ytterbium, and lutetium concentrates can be used as raw materials, and metal lanthanum can be used as a reducing agent. Under high temperature vacuum conditions of>1100 ℃ and<0.133Pa, metal ytterbium can be directly extracted by reduction distillation. Like samarium and europium, ytterbium can also be separated and purified through wet reduction. Usually, thulium, ytterbium, and lutetium concentrates are used as raw materials. After dissolution, ytterbium is reduced to a divalent state, causing significant differences in properties, and then separated from other trivalent rare earths. The production of high-purity ytterbium oxide is usually carried out by extraction chromatography or ion exchange method.

Barium carbonate (BaCO3), also known as witherite, is a chemical compound used in rat poison, bricks, ceramic glazes and cement.
The mineral is named after William Withering, who in 1784 recognized it to be chemically distinct from barytes. It occurs in veins of lead ore at Hexham in Northumberland, Alston in Cumbria, Anglezarke, near Chorley in Lancashire and a few other localities. Witherite is readily altered to barium sulfate by the action of water containing calcium sulfate in solution and crystals are therefore frequently encrusted with barytes. It is the chief source of barium salts and is mined in considerable amounts in Northumberland. It is used for the preparation of rat poison, in the manufacture of glass and porcelain, and formerly for refining sugar.It is also used for controlling the chromate to sulfate ratio in chromium electroplating baths.

Main purpose

1. Mainly used for producing PTC thermistor electronic components, manufacturing chip based components, semiconductor capacitors, etc.

2. Analyze iron in calcium, magnesium, manganese, and zinc, and measure halogens in organic matter. It is used for making barium salts, pigments, fireworks and flares, optical glass, rodenticide, pottery, porcelain, and as filler and water clarifying agent.

3. Used as a raw material for the electronic industry, for preparing capacitors, PTC electronic components, positive temperature coefficient thermistors, etc.

4. It is used as analytical reagent, preparation of fireworks and flare fuel, auxiliary material of ceramic coating and optical glass.

5. Used to treat excessive sulfate ions in chromium plating electrolytes, as well as in white passivation solutions for galvanized coatings, and can also be used to treat chromium containing wastewater.

6. Used as analytical reagents, water purifiers, rodenticides, and barium salts, as well as in the electronic industry, instrumentation, and metallurgical industries.

Manganese tetroxide is an important raw material for the production of manganese zinc ferrite soft magnetic materials in the electronic industry. It is mixed with iron oxide and zinc oxide in a certain ratio, and then sintered into a high-performance magnetic material – soft magnetic ferrite. This magnetic conductive material has a narrow residual magnetic induction curve and can be repeatedly magnetized. And its DC resistivity is very high, which can avoid eddy current losses. Therefore, it can be used to manufacture high-quality inductors, TV flyback transformer, telephone transformers, magnetic amplifiers, wireless rods, etc., as well as magnetic cores, disks, tapes, magnetic heads, etc. for computer information storage. There are various preparation methods for manganese tetroxide, which can be roughly classified into four categories based on process characteristics and reaction properties: roasting method, reduction method, oxidation method, and point solution method.

Barium titanate is a strong dielectric compound material with high dielectric constant and low dielectric loss. It is one of the most widely used materials in electronic ceramics and is known as the “pillar of the electronic ceramic industry”.

In summary, in the entire temperature range (<1618 ℃), barium titanate has five crystal structures, namely hexagonal, cubic, tetragonal, orthogonal, and cubic. As the temperature decreases, the symmetry of the crystal decreases. Above 130 ℃ (i.e. Curie point), barium titanate crystal shows paraelectricity, and below 130 ℃, it shows ferroelectricity.
