Water glass is an aqueous solution of silicate, which is as crystal clear as glass but as fluid as water. It is a soluble alkali metal silicate material composed of a combination of alkali metal oxides and silica.

Water glass plays an important role in industry, agriculture, technology and other fields. As a binder, water glass has occupied a place in the industrial field since its inception. It can be used to block the sewage leaked from the Fukushima nuclear power plant, or to repair cracks in brick walls; it also has anti-corrosion and acid resistance properties. , is an important material for acid-resistant floors and acid-resistant pools in industrial buildings; painting concrete pavements with water glass can also increase the frost resistance and water resistance of the pavement.

Carbon black, also known as carbon dark, is a kind of unformed carbon. It??s a light, loose and extremely fine black greasepaint with a veritably large face area ranging from 10 to 3000m2/g. It??s an deficient combustion of carbonaceous substances( coal, natural gas, heavy oil painting, energy oil painting,etc.) under conditions of inadequate air. Or products deduced from thermal corruption. Those made from natural gas are called?? gas dark??, those made from oil painting are called?? beacon black??, and those made from acetylene are called?? acetylene black??. In addition, there are?? trough black?? and?? furnace black??.

Chromium oxide is a basic inorganic chemical raw material. Its chemical name is chromium trioxide, Cr2O3. It belongs to the trigonal crystal system. If a hexagonal unit cell is taken, the unit cell parameters are 4.960x 4.960??13.584 and the axial ratio is 4.473. Cr2O3 has a ??-Al2O3 structure. This rigid crystal is composed of oxygen ions that are closely packed and M3+ ions fill the octahedral gaps formed by these close packings.It is known that the ionic radii of Cr3+ and O2- are 0.069nm and 0.132nm respectively, and the ratio of positive and negative ionic radii is 0.52, in the range of 0.414~0.732. Therefore, the coordination number of Cr3+ is 6, so it is in the octahedral gap.
