Issue 10/2015 - Silicon carbide ceramic membranes are expected to be industrialized

On March 10, the silicon carbide ceramic membrane technology developed by the Institute of Energy-saving Materials and Membrane Technology of Wuhan Institute of Technology entered the pilot stage, which can be put into production at the end of 2015 and is expected to be industrialized
in 2016.
At that time, silicon carbide ceramic membrane products will be mass-produced
for the first time in China.

According to reports, silicon carbide ceramic film is the focus of the current industrialization work of the Institute of
Energy-saving Materials and Membrane Technology.
This product is the highest-end product in the field of inorganic ceramic membranes and is a strategic emerging separation material
for the future.
Compared with other mainstream ceramic membrane products and organic membrane products, the silicon carbide membrane developed by them can be used in harsh environments such as strong acid and alkali (pH value 0~14) and high temperature (800 °C) that traditional membrane separation materials cannot be competed with, and the key indicators such as product flux and porosity (45%) have reached the international level
.
High-performance and high-throughput silicon carbide foam ceramic membrane has a very broad application prospect in the fields of chemical industry, medicine, plant extraction, metallurgy, chlor-alkali, dairy, sugar alcohol, high-temperature flue gas treatment, diesel vehicle exhaust treatment, PM2.
5 capture and collection, etc.
, and its industrialization will drive the development of
many downstream fields.

The product not only reaches the level of foreign imported products, but also has a great cost advantage
.
The core and key technologies of silicon carbide ceramic membranes, including support preparation technology, film coating control technology and porosity control technology, have unique innovations and independent intellectual property rights
.
In terms of process technology route, the silicon carbide ceramic membrane preparation process developed by Wuhan Institute of Technology also has great advantages, and the preparation cost is relatively low and pollution-free
.
