99% alumina oxide ceramic plate insulating hexagon bulletproof ceramic sheet

Ordinary alumina ceramics are classified into 99 porcelain, 95 porcelain, 90 porcelain, 85 porcelain, etc. according to the content of Al2O3. Sometimes the content of Al2O3 is 80% or 75%, which is also classified into ordinary alumina ceramic series. Among them, 99 alumina ceramic materials are used to make high temperature crucibles, refractory furnace tubes and special wear-resistant materials, such as ceramic bearings, ceramic seals and water valve sheets; 95 alumina ceramics are mainly used as corrosion-resistant and wear-resistant parts; In addition, due to the incorporation of part of talc, the electrical properties and mechanical strength are improved, and it can be sealed with metals such as molybdenum, niobium and tantalum, and some are used as electric vacuum devices.

Features & Advantages
1. High hardness.
2. High heat resistance: alumina ceramic has excellentthermal stability,which means that it is widely used in areas where resistance to high temperatures is essential.
3. Good wear resistance: alumina ceramic is the material of choice for alumina wear parts.
4. High electrical resistivity: alumina is an electrically insulating material.
5. High corrosion resistance: it is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.
