High-thermal-conductivity aluminum oxide ceramic substrate material and production method thereof
The invention relates to the technical field of aluminum oxide ceramic substrates, in particular to a high-thermal-conductivity aluminum oxide ceramic substrate material and a production method thereof.The high-thermal-conductivity aluminum oxide ceramic substrate material is prepared by filling a certain amount of lanthanum and barium elements into an aluminum oxide material, well mixing the lanthanum and barium elements with aluminum oxide and then performing high-temperature calcination processing.
