The tungsten switch contact is made of metal tungsten, which has good heat resistance, lower resistance, good chemical stability and other advantages, and can be very good circuit connection or break, thereby reducing the probability of electrical equipment failure.

1. Nano Tungstic Acid
Nano tungstic acid has a large specific surface area and significant surface effect. 

1. Overall Review of Tungsten Trioxide Produced by Extraction Method 

2. The main production process is using tungsten scheelite as raw material: roasting, grinding, alkaline pressure cooking to prepare sodium tungstate solution, purification and impurity removal, filtration of solid-liquid separation, sulfurization, acid adjustment filtration, extraction and back extraction, the ammonium tungstate solution is evaporated and crystallized, dried and sieved to obtain ammonium paratungstate (APT) product. After calcining APT, tungsten trioxide is obtained.

Tungsten heater is used in vacuum coating furnace, which is widely used to coat the surface of bottle lid.

Tungsten alloy application in military industry is mainly for aerospace, weapon and nuclear industry. Tungsten alloy (WHA) is heavy metal with main content of tungsten 90~97%, and other elements, such as copper, nickel, iron, manganese, and molybdenum.

1. Lithium Ion Battery in Daily Life
Lithium-ion batteries have become the main power source choice for portable electronic devices due to their large capacity, high voltage, and long life. In order to further satisfy people's demand for higher-performance lithium-ion batteries, it is an effective solution to find alternative electrode materials with better electrochemical characteristics.

1.Tungstic Acid
Tungstic acid is a yellow shiny sheet crystal or crystalline powder, soluble in water, insoluble in ethanol, slightly soluble in ammonia. 

Tungsten alloy application in civil industry including the grade of WNIFE, WNICU, WNIFECO, WNIFEMO, and the content from 90%W to 97%W.

Tungsten alloy shielding is made by tungsten nickel copper alloy or tungsten nickel iron alloy instead of lead or steel, and used to shield the radiations.
