Since the beginning of 2021, the prices of domestic bulk chemicals and metal materials have continued to rise in China. Affected by this, the price of aluminum ingots has risen from 1,860 USD/ton to 3,100 USD/ton. Large aluminum factories in China have adjusted their product structure. They cut the production capacity of industrial alumina powder.
Ceramic membrane, also known as a ceramic filter membrane, is a precision ceramic filter material with a multi-cavity structure that is made of powders such as white corundum powder (Al2O3), zirconia (ZrO2), and titanium oxide (TiO2) after high-temperature sintering. The ceramic membrane has excellent characteristics such as good chemical stability, acid and alkali resistance, high
In order to increase the adhesion of artificial corundum to other raw materials, it is necessary to attach a layer of iridium plating to the outer surface of artificial corundum to increase the adhesion to the raw materials during high-temperature extrusion. The current plating raw material of iridium is mostly water glass. This raw material
