要が生じた。Incidentally, in recent years, demand for Ni--Zn-based ferrite has been increasing in noise filter cores for 8MC countermeasures as the frequency of noise has become higher. Therefore, it became necessary to manufacture nickel-based ferrite at a lower price while maintaining quality.

ェライトを製造できる方法を得ることを目的とする。However, nickel oxide is expensive, and it is difficult to obtain nickel oxide with low impurity content (particularly cobalt content).The present invention was made to solve the above problems. The object of the present invention is to provide a method that allows the use of inexpensive nickel raw materials other than nickel oxide, thereby producing inexpensive and high-quality nickel-based ferrite.

を成分として含むフェライトの製造方法において、水酸
化ニッケルをニッケル原料として使用する方法である。The method for producing nickel-based ferrite of the present invention is a method for producing ferrite containing nickel as a component, in which nickel hydroxide is used as a nickel raw material.

製造する。The specific manufacturing method can be the same as conventional methods. For example, other raw materials such as ferric oxide, zinc oxide, copper oxide, etc. and nickel hydroxide are weighed and mixed to have a predetermined composition, and then temporarily mixed. Ferrite is manufactured through firing, crushing, granulation, molding, and main firing.

て原料変更に伴う製造プロセスに与える影響が小さい。In the method for producing nickel-based ferrite of the present invention,
Nickel hydroxide (Ni(O)l)a) is nickel oxide (
Since it contains only one molecule of water (H,0) more than nickel (Nip), the influence on the manufacturing process due to a change in raw materials is smaller than when other nickel raw materials are used.

ェライトが得られる。For example, if nickel chloride (NiCQz) is used, chlorine gas (CQ2) is generated during firing, which requires major changes to manufacturing equipment, such as adding an exhaust system and changing firing conditions, but using nickel hydroxide Then, only water vapor is generated, and nickel-based ferrite can be obtained without making any changes to conventional manufacturing equipment that uses nickel oxide (NIP).

1 ton of Ni-Zn-Cu-based ferrite obtained by mixing, pre-calcining and pulverizing at a ratio of +101%)
A specimen was obtained by pressing at /- and firing at 1060°C. This specimen had an initial magnetic permeability μl of 700 and a Curie temperature Tc of 150°C. This property is equivalent to that of ferrite made with the same composition using nickel oxide (Nip).

つフェライトが得られた。The mixing ratio of raw materials is not limited to the above, but Fe, O, is 4
7-49.5%, ZnO 15-35%, Ni(OH)
2 is 10-25%, CuO is 4-10% (all mo1
%) and a ferrite having a characteristic μ in the range of 100 to 2000 was obtained.
また焼成温度は950〜1200℃の範囲で、組成と必
要な特性に適した温度を選択することが可能である。Further, the firing temperature is in the range of 950 to 1200°C, and it is possible to select a temperature suitable for the composition and required properties.
すなわち上記実施例において、従来の酸化ニッケルを使

とが可能となり、製造コストが低減する。That is, in the above examples, ferrite having the same mechanical characteristics as conventional ferrite using nickel oxide was easily obtained. Also, nickel hydroxide (Ni(Oll)2
) had better sinterability during firing. Therefore, it becomes possible to relax the pressing conditions and firing conditions compared to the conventional ones, and the manufacturing cost is reduced.
なお、水酸化ニッケル(Ni(OH)、)の使用可能な
組成範囲は上記実施例の範囲のみに限られない。Note that the usable composition range of nickel hydroxide (Ni(OH)) is not limited to the range of the above embodiments.
酸化ニッケルと比較して水酸化ニッケルは水(N20)
1分子を多く含むだけの違いであるので、酸化ニッケル

ような状況は、外観上および特性上−切a測されなかっ
た。Compared to nickel oxide, nickel hydroxide is water (N20)
Since the difference is only that it contains more one molecule, nickel hydroxide can also be used in the entire composition range where nickel oxide can be used. In fact, in the above-mentioned example, during the trial production in the above-mentioned composition range, no situation in which the composition of nickel hydroxide was at the limit of use was observed in terms of appearance and properties.
