The traditional preparation of tungsten alloys is mostly based on sintering technology, which leads to a series of problems such as low densification, uneven microstructure and limited composition of tungsten-based alloys. It is mainly reflected in the slow preparation speed, low efficiency and high preparation cost.

As a sputtering target for copper wiring diffusion barrier layer, W-Ti alloy has many requirements in structure and properties. A large number of experimental results show that the grain size and Ti-rich phase content of WTi alloy structure are the main factors affecting the performance of the barrier layer.

Tungsten plays an important role in high temperature materials and functional materials. Widely used in the electronics and light source industry, in the aerospace, foundry, weapons and other departments for the production of rocket nozzles, die-casting molds, armour-piercing core, contacts, heaters and heat shields.

Molybdenum is a trace element of life needed by organisms. Lack of molybdenum in the human body can lead to a series of diseases. Such as Keshan disease, kidney stones, Kashin-Beck disease, hypertension and diabetes. In particular, molybdenum deficiency can increase the incidence of cancer and cancer.
