Title:
MANUFACTURE OF CERAMIC RESISTOR
Document Type and Number:
Japanese Patent JP3541113
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve workability by reducing the solidification of slurry, and to provide a manufacturing method of a zinc oxide ceramic resistor having improved electric characteristics.
SOLUTION: In the manufacturing method of a ceramic resistor which is formed by performing the processes of mixing, granulating, molding and firing, etc., of the power having zinc oxide as the main component and the aluminum oxide (3.0 to 40mol%), magnesium oxide (2.0 to 40mol%) and silicon oxide (0.1 to 10mol%) as additional components, the whole quantity or a part of magnesium oxide is replaced with magnesium nitrate, and the whole quantity of the magnesium oxide and the magnesium nitrate is made equivalent to the original magnesium oxide.
