5), a powder obtained by reducing alkali titanate with carbon (Japanese Patent Publication No. 62-3767), and a powder obtained by coating potassium titanate with antimony-doped tin oxide are known. Carbon or potassium titanate reduced with carbon has a carbonaceous surface, so it is more hydrophobic than general inorganic fillers, and when added to plastics, it blends well with other pigments, etc., and is less likely to be dispersed during mixing. Problems arise such as color separation and detachment in molded products. In addition, regarding the powder made by reducing potassium hexatitanate developed by the present inventors, 80
When the temperature exceeds 0°C, the original fibers tend to break. Regarding potassium titanate fibers coated with a conductive substance, the adhesion between the conductive substance and the substrate is a problem. Furthermore, there is a problem in that conductive materials using alkali titanate fibers as a base material cannot be used in applications where the presence of alkali is to be avoided, such as polycarbonate, engineering plastics containing flame retardants, and antistatic applications related to semiconductors.

う用途に使用出来なくなる。The fibrous titanium oxide or hydrated titanium oxide used in the present invention may be of any tetragonal crystal type, such as amorphous, anatase, or rutile, and has an average length of 0.3 μm to 20 μm.
00 μm, an aspect ratio (major axis/minor axis) of 3 to 200, and an alkali content of 1 wt% or less. If the average length is less than 0.3 μm, the amount added to the conductive composite will be large. If the average length exceeds 2000μ, the fibers will become entangled with each other, resulting in poor dispersion in the composite. Regarding the aspect ratio, if it is less than 3, the amount added will increase and no improvement in mechanical properties such as reinforcing properties will be observed. 200
If it exceeds this amount, it becomes easy to break during compositing, and the dispersibility also decreases. Regarding alkali content such as potassium and sodium, if it exceeds lvt%, it will easily break during heat reduction.
The fibrous conductive titanium oxynitride of the present invention cannot be used in applications where alkalis are averse.

に、プラスチックに添加した場合、機械的強度。If the temperature exceeds 1000℃, the fibers will sinter and cannot maintain their original shape and lose their reinforcing properties.In this temperature range, the reaction time is relatively short, 0.5 to 6 hours.Contains ammonia. Regarding the flow rate of the reducing gas, as long as carryover is suppressed, the higher the in-furnace linear velocity, the more uniform the powder can be obtained, but unless the in-furnace linear velocity is at least 0.5 c/see or higher, the reaction will not proceed uniformly. The titanium oxynitride fibers obtained in this way can be produced by changing the reaction temperature, time, and flow rate of the reducing gas.
A colored reinforcing powder is obtained with a wide range of conductivity from cm to 10' Ω·am. Also, this fiber is Ti(lxN
It has a composition of y (1< x + y<2), and contains 4~
39 wt%, 1 to 20 t% of nitrogen (O7N weight ratio 39
~0.2) Contains. Over 39wt% oxygen, 1w nitrogen
If it is less than t%, it will not show conductivity, and if it is less than 4wt% oxygen and 20vt% nitrogen, it will not be able to maintain its original shape. Conductivity can be imparted with a smaller amount of addition than by compounding with an inorganic substance (such as an inorganic substance). Furthermore, when added to plastics, mechanical strength.
