Ceramic material for metal and high-temperature glass insulator welding encapsulation mold
The invention discloses a ceramic material for a metal and high-temperature glass insulator welding encapsulation mold. The ceramic material contains the following ingredients: carbon, at least one of aluminum, aluminum oxide and aluminum nitride, at least one of boron carbide, boron nitride, titanium, titanium carbide, titanium carbonitride and titanium dioxide, at least one of silicon, silicon nitride and calcium oxide, and at least two of yttrium oxide, cerium oxide, chromium carbide, lithium, lithium carbonate, lanthanum oxide, nickel, molybdenum carbide and zirconium oxide. The ceramic material has the advantages that the ceramic material for the welding encapsulation mold is used for encapsulating metal and a high-temperature glass insulator, the performance is excellent, the usage temperature reaches up to about 1,100 DEG C, the ceramic material does not deform at high temperature, is good in cold-hot rapid denaturation, does not adhere melted high-temperature glass insulators and is not oxidized, the problem that oxidized ceramic dust is adhered to the glass insulators cannot occur, carburization of the surface of the metal cannot occur, the quality of product is not affected, and the service life is over 10 times that of a graphite encapsulation material under the same conditions, so that the ceramic material is the best material for replacing graphite encapsulation materials at present.
