Microcrystalline glass brazing filler metal for ceramic connection, preparation method of glass ceramic brazing filler metal and ceramic connection method
The invention discloses microcrystalline glass brazing filler metal for ceramic connection, a preparation method of the microcrystalline glass brazing filler metal and a ceramic connection method. The microcrystalline glass brazing filler metal for ceramic connection is a multi-phase mixture mainly composed of a glass phase and Al-B-O series oxide crystals. The glass brazing filler metal is prepared from, by mass, 35-45% of Al2O3, 25-35% of B2O3, 15-25% of SiO2 and 3-15% of alkaline earth metal oxide. The preparation method specifically comprises the following steps of: mixing the raw materials well, rapidly smelting the mixture into a glass melt, and then carrying out water quenching and grinding. According to the ceramic connection method, the microcrystalline glass brazing filler metal provided by the invention is used for connecting ceramic materials. When the microcrystalline glass brazing filler metal is used for connecting a ceramic material with aluminum oxide as a matrix, slender whiskers are generated through the reaction among components in the glass brazing filler metal and the reaction between the brazing filler metal and oxide ceramic base metal to realize stable and reliable connection of the base metal, the strength of a connection joint is high, and the residual stress at the joint is small.
本发明公开了陶瓷连接用微晶玻璃钎料及其制备方法和陶瓷连接方法。陶瓷连接用微晶玻璃钎料主要是由玻璃相和Al‑B‑O系氧化物晶体组成的多相混合物，该玻璃钎料的原材料组成成分按质量百分含量计包括：35～45％Al2O3、25～35％B2O3、15～25％SiO2、3～15％碱土金属氧化物。该制备方法具体包括将原料均匀混合，快速熔炼为玻璃熔体，然后进行水淬、磨粉。陶瓷连接方法，采用本发明提供的微晶玻璃钎料连接陶瓷材料。利用上述微晶玻璃钎料连接以氧化铝为基体的陶瓷材料时，通过玻璃钎料中组元间的反应、钎料与氧化物陶瓷母材之间的反应生成细长晶须实现母材稳定、可靠的连接，连接接头强度高，接头处残余应力小。
