Material Introduction

Alumina (Al2O3) is one of the most widely specified, general-purpose technical ceramics. All alumina are very hard and wear resistant, with high compressive strength even against extreme temperatures and corrosive environments. Alumina are also excellent electrical insulators and are gas tight. Aluminum Oxide Ceramic is produced by firing a tightly packed powder form of Al2O3 which includes some binder material. Commercially available grades range from 90% up to 99.8% with the higher purity generating somewhat higher hardness. It is possible to machine alumina using diamond grinding techniques. Polishing is also possible, with the degree attainable affected by alumina grain size and production technique, whether pressed or extruded.

  High Hardness   Low Coefficient of Thermal Expansion
  Excellent Electrical Insulator   Mechanically Stable at High Temperature
  Good Thermal Shock Resistance   High density, non-porous and vacuum tight
  Resists Abrasive Wear and Chemical Attack   ......

Products application

What is Ceramic Pipe Sleeve?

The main raw material of wear resistant ceramic ring is a special kind of ceramic with AL2O3 as the and the rare metal oxide as the flux, which is melted by high temperature at 1700 °C. The Ceramic Sleeves Lined Pipe as a whole part, and then assemble it into the steel pipe with our high-strength-temperature-resistant epoxy adhesive.

Alumina ceramic tube is of high wear resistance, acid and alkali resistance, effectively prolong the service life of equipment and considered to be the best choice of anti-wearing and anti-corrosion material; Wear resistance of ceramic is 10 times than that of special manganese, 10 times to high chrome cast iron; Hardness is much higher than that of wear-resistant steel and stainless steel. Application: Oil, mining, steel and power industry.
