XTL sintyron beryllium oxide ceramic plate sheet

Some performance characteristics of beryllium oxide ceramics have the necessary needs in the military field, it is difficult to be replaced by other materials, so for a long time in the raw materials are strictly controlled, products are almost only for military needs, rarely used for civilian use, and lost the opportunity to promote. Today, beryllium oxide ceramics can be very precise structural parts, and the structural parts can still work normally at a high temperature of more than 2000 degrees Celsius, at the same thickness, beryllium oxide ceramic substrates can be used more frequently than alumina substrates 20% higher.
