Microporous ceramics are a kind of silicate products. The raw materials used are barren clay, waste slag, power plant fly ash and glass plant waste, which will play an important role in protecting the environment and saving resources. Microporous ceramic is a functional structural ceramics. Microporous ceramics, such as adsorbability, permeability, corrosion resistance, environmental compatibility and biocompatibility, are widely used in the filtration of various liquids, filtration of gases, and immobilization of biological enzyme carriers and biocompatibility carriers, especially in environmental engineering, such as industrial water and domestic water treatment, The purification of sewage and so on.

With the development of economy, energy consumption for temperature regulation has increased rapidly. As an effective means of heat insulation, energy saving and environmental protection, solar panels for automobiles and building glass are becoming more and more popular in recent years.

Researchers found that the atmosphere around tungsten alloy billets plays a key and decisive role in sintering quality during sintering. In particular, when tungsten alloys are sintered in large quantities, as tungsten alloys contain alloy additives, a large number of impurities are discharged during sintering, the greater the amount of furnace loading, the greater the impurity of the discharge and the worsening of the sintering atmosphere. The protective gas can take away a large amount of impurities produced in the sintering process and ensure the sintering quality. Therefore, on the one hand, the need for hydrogen excess to meet the requirements of sintering, on the one hand, need to reduce the amount of hydrogen to reduce the cost, which is a dilemma.

At present, a method for manufacturing a yttrium tungsten electrode is mainly to obtain a metal blank by a powder metallurgy method. There are three kinds of traditional mixing processes.
