<p>PURPOSE:To improve yield during slurry granulation by suppressing a rise in slurry viscosity after wet mixture for manufacturing a voltage nonlinear resistor for high voltage use containing silicon oxide of a specified value or more. CONSTITUTION:A title resistor is manufactured which mainly contains zinc oxide and silicon oxide of 4.0mol% or more, and another one or more of metal oxides. Zinc oxide power and metal oxide powder other than silicon oxide powder are primarily mixed by wet method, and next at least zinc oxide powder and silicon oxide powder are added to this primary mixture and secondarily mixed by wet method. At the point of time of secondary mixture, aluminum ions, an organic binder, etc., can be added. The slurry after secondary mixture is granulated, and this granulation powder is molded: this molding is baked.</p> |
