​As a typical molybdate, ammonium heptamolybdate is also called ammonium paramolybdate. It is a colorless to light green crystalline powder composed of transition metal molybdenum, non-metallic oxygen, hydrogen and nitrogen. It is an ammonium molybdate composed of ammonium ions and heptamolybdate ions. Its name can be divided into Ammonium heptamolybdate or Ammonium paramolybdate. Its chemical formula is (NH4)6Mo7O24, its molar mass is 1163.9g/mol, and its CAS registration number is 12027-67-7 or 12054-85-2 (tetrahydrate).

​As a representative product of refractory metal molybdenum, molybdenum bar is a rod-shaped product with high-purity molybdenum as the main material. It is often called molybdenum rod or molybdenum rod in the industrial field. The purity of molybdenum bar is as high as 99.7%. Due to its thermal, mechanical, chemical and electrical properties, it has become the core basic material of many industries such as smelting and power equipment.

​The principle of molybdenum metal bar in the manufacture of vacuum devices is mainly based on the unique physical and chemical properties of molybdenum matching the working requirements of vacuum devices. The following is an analysis from the material properties, device working environment and specific application principles: I. The core physical and chemical properties of molybdenum metal bar and the adaptability of vacuum devices:

Roasted molybdenum concentrates, also known as molybdenum trioxide or industrial molybdenum oxide, generally refers to roasted sand after molybdenum concentrate is roasted. Molybdenum concentrate is usually oxidized and roasted at 630℃~700℃ to convert molybdenum sulfide into industrial molybdenum trioxide, which is the raw material for producing ferromolybdenum and ammonium molybdate. In recent years, China has produced about 200,000 tons of roasted molybdenum concentrates each year, with a value of about 36 billion yuan, of which about 30% is used to produce ammonium molybdate, and then to produce molybdenum chemicals and molybdenum metal products, and the rest is used to process ferromolybdenum raw materials. Roasted molybdenum concentrates are divided into ordinary and high-soluble. In addition, according to the latest national standard classification, it is more refined. In addition to the above two categories, there are also blocks. We will not introduce it in detail here. Today we will mainly talk about the two types of ordinary and high-soluble in detail.

On April 14, 2025, the opening ceremony of the key projects in the first quarter of Taihe District and the opening ceremony of Liaoning Hongtuo Technology's 3,000 tons of molybdenum metal deep processing project were held. The ceremony brought together leaders from Jinzhou Municipal Party Committee, Municipal People's Congress, Municipal Government, District Party Committee and District Government, and heads of relevant departments. At the same time, representatives of more than 30 key project units such as CITIC Jinzhou Metal, Jinzhou Dongji Motor, Jiamai (Liaoning) New Materials, Shengong Semiconductor, and Wande Packaging attended and witnessed this important moment together.

On September 10, Liaoning Hongtuo New Materials Technology Co., Ltd. was interviewed by the "National 100 Cities and 100 Media Looking at Jinzhou" event. The event was attended by leaders of the district committee, the development zone, Jinzhou Metal New Materials Industry Association, Jinzhou News Media Group and other leaders and media guests to learn about our company's development history, production process and future plans.

On February 9, Xiong Maoping, member of the Standing Committee of the Provincial Party Committee and Minister of the Organization Department, came to our city to supervise and investigate the implementation of the New Breakthrough three-year Action on All-round Revitalization, and encouraged Party members, cadres and the masses to show greater responsibility and achievements in fighting and winning the "Liaoshen Campaign" in the new era, so as to ensure a good start of the new Breakthrough three-year action on all-round revitalization. Deputy Party Secretary, Mayor Wang Xinyu accompanied the supervision research.

Entering Liaoning Hongtuo New Material Technology Co., Ltd.: The clean and tidy large courtyard, the staggered office building and standardized workshop, as well as gym and hotel -style breaks ... Is this a company that produces industrial products? There seems to be no black smoke. In large environmental protection processing equipment, it is said that the hot water that can be recycled.
