Cleaning process of beryllium oxide ceramic

Abstract

The invention discloses a cleaning process of beryllium oxide ceramic. The process has the following process flow of: preparing oil-removing solution, removing oil with ultrasonic waves, filtering the solution and treating scrap materials, cleaning with flowing water, cleaning with the ultrasonic waves, drying, and taking the beryllium oxide ceramic out. The cleaning process is simple, easy to realize and low in cost; toxic dust attached to the beryllium oxide can be effectively washed off; and the hurt to a human body caused by the beryllium oxide is reduced.

Description

technical field

[0001] The invention relates to the fields of microwave electric vacuum technology and electric vacuum material technology, in particular to a cleaning technology for beryllium oxide ceramics. Background technique

[0002] Electric vacuum ceramics include oxide ceramics, silicate ceramics, nitride ceramics, etc. Oxide ceramics include alumina (Al 2 o 3 ) porcelain, beryllium oxide (BeO) porcelain, magnesium oxide (MgO) porcelain, zirconia (ZrO) 2 ) Porcelain etc. The main component of oxide porcelain is a single oxide crystal, with high purity crystal phase and less glass phase. The purity of raw materials is high, and the sintering temperature is also high, so the electrical, thermal and mechanical properties of porcelain are good.

[0003] Beryllium oxide ceramics are made of beryllium oxide powder, adding trace amounts of MgO, Al 2 o 3 It is sintered with other additives, and the sintering temperature reaches 1800°C to 1850°C. The mechanical streng...
