Alumina-fiber-enhanced beryllium oxide ceramic-based composite material and preparation method thereof
The invention discloses an alumina-fiber-enhanced beryllium oxide ceramic-based composite material and a preparation method thereof. The material is characterized in that the material is prepared from the raw materials of, by weight, 3-5 parts of phosphorus pentoxide, 10-15 parts of modified alumina fiber, 70-80 parts of beryllium oxide, 7-9 parts of hafnium dioxide, 4-6 parts of titanium dioxide, 0.02-0.03 part of t-butyl hydroperoxide, 4-6 parts of butadiene, 1-2 parts of polyvinylpyrrolidone, 1-2 parts of sodium tripolyphosphate, 0.1-0.3 part of diacetone acrylamide, 2-3 parts of polyvinyl alcohol, 20-30 parts of ethanol, and 30-50 parts of deionized water. According to the invention, the alumina fiber processed through an antioxidant treatment is adopted as a ceramic enhancement phase, and has the properties of enhancing the toughness, mechanical properties, wear resistance, hardness and high-temperature resistance of ceramic. With the added titanium dioxide, ceramic acid resistance is enhanced. With the added phosphorus pentoxide, a blank protection effect is provided during a ceramic manufacturing process, air oxidation is reduced, and blank damage is reduced.
