Density: >9.8 g/cm3
Working temperature: >1100°C
Content Technique Density Size
Mo >=99.95% Forging >=10.1g/cm3 (10-130mm) dia. x (10-2mm)
Mo >=99.95% Sintering >=9.8g/cm3 (100-500mm) dia. x (50-700mm)

 Most molybdenum crucible is produced by sintering pure molybdenum. The reason to use pure molybdenum as raw material is to prevent other metals melting in the molybdenum crucible from mingling impurities. Because molybdenum crucible has high-temperature resistance, low pollution and other excellent properties, molybdenum crucible is widely used in various industries. According to the required diameter, thickness, tilt angle, we can produce a various shapes and sizes of molybdenum crucible to meet your need.

Molybdenum crucible is a very important and essential tool in many industries. Molybdenum crucible can be used in smelting and rare earth metallurgy, mechanism process, electronics, artificial crystals, coating technology industries, such as: crystal materials, the sapphire growth, vacuum coating production, quartz glass melting furnace, smelting furnace and silicon crystal furnace and so on.

China Molybdenum Wire Introduction

Molybdenum wire is an important product among molybdenum finished products and its total production accounted for 13% of molybdenum deep processing product’s total output. China molybdenum wire is divided into pure molybdenum wire and doped molybdenum wire and the diameter is generally between 0.051 to 0.350mm. The brands of China molybdenum wires are Mo1, Moδ, Mo2, Mo3, Mo3 δ. There Mo1 and Mo2 are pure molybdenum and Mo3 is doped molybdenum wire which is doped with Ca, Mg and other elements. Molybdenum wire main production processes are mainly as follows: First, through the powder metallurgy method can obtain molybdenum powder and the metal powder after sintering will produce molybdenum bar.

Secondary, the molybdenum bar is processed rotary forging or rolling to obtain molybdenum rod. Finally, after tensile process the manufacturers can manufacture molybdenum wire with required diameter. Compared with foreign molybdenum wire, there are some shortages on China molybdenum wire. The main problem is simple product structure. Besides, molybdenum billet is lighter and the average length of molybdenum wire is shorter. Further, uneven thickness of molybdenum wire is obvious and the surface has some shortcomings, such as trench, burr and easy to break and other.

 China's molybdenum wire trade developed rapidly in recent years, from 1996 to 2000, molybdenum wire exports accounted for 22.3% of imports and exports total trade volume. The exported molybdenum wire is mainly used in the picture tube industry, molybdenum coating industry and wire cutting industry.

At present, China's molybdenum wire production technology and equipment have been very perfect, and with the development of production technology, China molybdenum wire can not only meet the domestic market, but also can demand foreign market, so there are more than 10 tons molybdenum wire for export.

However, China's molybdenum wire in quality, innovation and other aspects still has some problems. In order to accelerate the development of molybdenum wire, China should first accelerate the development of molybdenum leading company to concentrate other scattered enterprises, in order to scale, multi-species, high-quality produce molybdenum wire. In addition, the molybdenum companies should through purchase the advanced production equipment and improve production methods to improve the quality of molybdenum wire products. Finally, they should combine with market demand to develop new varieties.
