isostatic pressing abrasive Alumina Ceramic Sleeve valve
Reputation depends on quality, quality comes from Hard!
Alumina Ceramic:
There is also a β-Al 2 O 3 which has ion conductivity (allowing Na to pass) and a sodium-sulfur battery made of β-alumina as an electrolyte. Since such a battery has a large amount of electric power per unit weight and can discharge a large current, it has a broad application prospect. The negative electrode of the battery is molten sodium, the positive electrode is sodium polysulfide (Na2Sx), and the electrolyte is β-alumina (sodium ion conductor).
The battery can be used in a temperature range of 620 to 680K, and its storage capacity is 3 to 5 times that of the lead battery. The use of β-Al2O3 ceramics as a separator for the production of brine to produce caustic soda has the characteristics of high purity and low pollution. Alumina is suitable for a variety of wet and dry processes, polishing the rough surface of any workpiece.
It is one of the most economical abrasives. This sharp-edged synthetic abrasive has a hardness second only to diamond, and is especially suitable for use when iron contamination is critical. For the roughest cuts, it can also be made into a pebble shape to handle extremely precise workpieces to achieve extremely low roughness. Due to its high density, sharp, and angular structure, it is one of the fastest cutting abrasives available today.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
