Application of alumina are very wide, include but not limited to following:
1. The main components of ruby and sapphire are alumina, which show different colours because of other impurities. Ruby is red with chromium oxide, while sapphire is blue with iron oxide and titanium oxide.

2. Among the main components of bauxite, the content of alumina is the highest. In industry, bauxite is purified into alumina by Bayer process, and then converted from Hall-Heroult process to aluminium metal.

3. Alumina is the reason why metallic aluminium is not easily corroded in air. Pure aluminium metal reacts easily with oxygen in the air to form a thin alumina film covering the surface of aluminium exposed to air. This alumina film prevents aluminium from being oxidized further. The thickness and properties of this oxide film can be enhanced by a process called anodic treatment (anodic anticorrosion).

4. Aluminum is a good conductor of electricity and heat. Aluminum crystal form diamond is suitable for grinding materials and cutting tools because of its high hardness.

5. Alumina powder is often used as a medium for chromatographic analysis.

As per the define of the IEC (International Electrotechnical Commission), the explosion working environment is classified as gas explosive and dust explosive. When we talking about the explosion proof standard electrical equipment, we are talking about the equipment used in the various gas explosive working environment. And then according to the existence time of the gas explosive, the working environment is classified to 3 zones as below:
1. Zone 0 – Under normal operation condition, the gas explosive exists continuously. Always more than 1000 hours per year.
2. Zone 1 – Under normal operation condition, the gas explosive exists sometimes. More than 10 hours buy less than 1000 hours per year.
3. Zone 2 – Only under abnormal operation condition, the gas explosive exists. Always less than 10 hours per year.

The Zone 0 always represents some airtight space such the gas storage tank. On the oilfield, the Zone 1 represents the area around the drilling rig. And the area which includes the space for mud recycling system, mud pump, water tanks and other drilling field equipment. As per the minimum ignition power required, the gas explosive are classified as 4 degrades separately Ⅰ,ⅡA, ⅡB, ⅡC. This classification can also be treated as the equipment group. The equipment used in group Ⅰ is for mining industry. Group Ⅱ is for other industry working environment. The equipment used in group ⅡC can also be used in ⅡA, ⅡB which means the equipment in Group ⅡC has a higher explosion proof level.
GN could provide the solids control equipment with motor and control panel explosion proof certified. The explosion proof level is ExdⅡBT4 which could meet the demand of gas explosive Zone 2.
