Tungsten Alloy Nail 409

Tungsten alloy nail has the advantages of quick sinking speed, accurate target, quick positioning, etc. It can usually be used in the military field and fishing field. It is one of the best-selling products in the market. Characteristic Tungsten alloy nail is made of high density, high melting point tungsten alloy, containing 95% tungsten, 3.5% nickel and 1.5% iron, higher density than lead, smaller volume, non-toxic and non-polluting. Because it is very similar to a bullet, it is relatively long,…

Tungsten Alloy Nail Shape 445

Tungsten alloy nail shape is a small, fish-like sinker that looks like a needle tip. It has a non-toxic environmental protection and a long service life. It can be used as a balancing piece for plastic hoses and can also be used on other fishing gear. Characteristic Tungsten alloy nail shape is made of high-density tungsten alloy, and its volume is smaller than that of the lead fishing sinker, which reduces the resistance. Non-toxic and environmentally friendly, there is no…

Tungsten Alloy Water Drop Shape 416

Tungsten alloy water drop shape is non-toxic and safe to use. It is an ideal substitute for lead and fish sinker. It can quickly enter the grass and is quieter and more accurate than any other fish sinker. Characteristic Because the density of tungsten alloy is higher than that of lead, tungsten alloy water drop shape is smaller in size than the same weight of lead fishing sinker. The same weight of tungsten alloy fishing sinker is 25% smaller than…

Tungsten Alloy Bullet Shape 359

Tungsten alloy bullet shape is a tungsten alloy designed as a bullet. It has the characteristics of high density, small size, and non-toxic environmental protection. It is widely used on fishing gear and is popular among anglers. Preparation Tungsten alloy bullet shape is made of high quality tungsten powder. The bullet shape is formed using injection molding techniques. The tungsten content is 97% pure tungsten. Applications Tungsten alloy bullet shape can pass through the complex grass, and can be widely…

High Purity BTO Powder 291

High purity BTO powder has the same determining procedures of ammonia as described in “99.9% Nano Blue Oxide”. There are several matters needing attention in this experiment. Notices of determination experiment of ammonia content in high purity BTO powder are shown as follows: 1. The order of connection of the conical flasks must not be wrong. Air should be sniffed through the long tube, and then flow out from the short tube. Otherwise, the liquid will be pumped into the…

99.9% Blue Tungsten Oxide Nanopowder 251

99.9% blue tungsten oxide nanopowder’s quality is guaranteed by determining ammonia content to meet clients’ requirements. Therefore, people studied the determination method of ammonia in blue tungsten oxide. It has been proved by experiments and practice that the following methods may meet production control to analyze ammonia indicators in blue tungsten oxide. 1. Instruments and Reagents Four conical flasks (300ml) with double- hole rubber plugs. A flow meter cylinder. C(1/2H2SO4)=0.5mol/L H2SO4 standard solution; C(Noah)=0.5mol/L NaOH standard solution. 30% NaOH solution.…

99.95% Blue Tungsten Oxide Nanopowder 254

99.95% blue tungsten oxide nanopowder’s NH3 content is reasonably controlled to better ensure the stable phase composition of blue tungsten oxide, which is the method for controlling the stability of BTO on phase composition since the 1990s. In the 1980s, the quality control of blue tungsten oxide producing process was based on controlling the oxygen index to ensure the stability of phase composition of blue tungsten oxide. Currently, domestic and foreign customers have different requirements for NH3 content. Some requests…

Tungsten Blue Oxide 247

Tungsten blue oxide is the full name of TBO, which is not a defined tungsten compound, but a powdery mixture of tungsten trioxide, β-tungsten oxide (blue tungsten oxide), γ-tungsten oxide (violet tungsten oxide), ammonium tungsten bronze and hydrogen tungsten bronze. And the chemical composition and physical properties of BTO are changing. TBO may be produced by calcinating ammonium paratungstate (APT) in the airtight space or under hydrogen atmosphere/hydrogen-nitrogen mixed gas. The composition of TBO varies greatly on the basis of…

84% Yellow Tungsten Oxide 597

84% yellow tungsten oxide may be used to produce high quality ultrafine tungsten carbide (WC) powder by carbonization method. The producing processes are shown as follows: 1. Mix yellow tungsten oxide (mass fraction of 84%) and carbon (mass fraction of 16%) by mixer, and granulate to particle (grain size of 3mm) by granulator, then dry and mixed material is obtained. 2. Move material to the rotary furnace for continuous reduction/carbonization, the original material changes during the reaction: WO3→WO2.9→WO2.72→WO2.0→W→W2C→WC WO3 was…
