There are many kinds of antimony compounds, and the application range is quite wide. It has applications in medicine, electronics, glass manufacturing, flame retardant, ceramics, enamel, printing and dyeing, chemical engineering, and chemical analysis. Sodium gluconate is the drug of choice for the treatment of kala-azar, with good efficacy and few side effects. It can be prepared by the action of sodium gluconate and citric acid. Potassium sulphate (salt) and sputum-273 (sodium bismuth subsodium gallate) are all drugs for the treatment of schistosomiasis. The former achieves the goal of eliminating schistosomiasis by disturbing the metabolism of schistosomes; the latter can transfer the schistosomiasis in the mesenteric vein to the liver, block the small blood vessels of the liver, be surrounded by phagocytic cells, and finally destroy. Potassium bismuth tartrate is prepared by crystallization of antimony trioxide and potassium hydrogen tartrate solution; 锑-273 is prepared by the action of hypogal acid and antimony trioxide in a neutral solution. The compounds InSb, AlSb, GaSb, Sb 2 Se 3 , Sb 2 Te 3 , etc. formed of cerium and Group IIIA and Group VIA elements are all excellent semiconductor materials. Antimony and indium metal at high temperature fusing, melting and then purified by single crystal indium antimonide that is, the single crystal can be made of IR detector elements with specific properties. Cerium oxide (Sb 2 O 3 ), sodium citrate (NaSbO 3 ), sodium hydrate hydrate (NaSb(OH) 6 ), etc. can be used as clarifying agents in glass production, except that Sb 2 O 3 is used for ordinary glass. NaSbO 3 and NaSb(OH) 6 are used for picture tube bulbs, optical glass and various advanced glasses. When Sb 2 O 3 is used as a glass clarifying agent, it should be used together with nitrate. The principle is that it is oxidized by oxygen released by nitrate at a temperature of 1000 to 1200 ° C; and oxygen is released when the temperature reaches 1300 ° C or higher. Clarification; Sb 2 O 3 becomes Sb 2 O 5 again during cooling, so that oxygen bubbles are absorbed and removed. Generally, the amount of the glass species Sb 2 O 3 is 0.05% to 0.5%. NaSbO 3 and NaSb(OH) 6 are better than Sb 2 O 3 as a glass clarifier. They are used alone and function similarly to Sb 2 O 3 . They also generate Sb 2 O 3 at high temperature to release oxygen. When cooled, Sb 2 O 3 is again converted into Sb 2 O 5 to absorb oxygen bubbles, thereby achieving the purpose of clarifying the glass. A certain amount of Sb 2 O 3 , sulfur, and carbon powder is added to the soda lime glass, and after smelting, heat treatment is performed by color development to obtain a blush glass which is inexpensive and easy to popularize. This type of glass is used as signal glass and art glass. Further, the chalcogenide glass made of Te-Ge-Sb-S is a semiconductive glass for switching. Lanthanide flame retardants play an increasingly important role in inorganic flame retardants. Sb 2 O 3 , non-colloidal Sb 2 O 5 , colloidal Sb 2 O 5 , SbCl 3 , NaSbO 3 , etc. have developed a series of different compositions, different characteristics, used in different occasions, widely used in rubber, plastic, chemical fiber , carpets, paints and other flame retardant products. With the development of Sb 2 O 3 ultra-fine technology, we are able to obtain Sb 2 O 3 with a finer particle size, which has better addition performance and less deterioration of the physical properties of the flame-retarded substrate. The average particle diameter of the colloidal Sb 2 O 5 is only 0.03 um, which is about 1/100 of the particle size of the general Sb 2 O 3 . Since it is extremely fine, the physical properties of the resin substrate are not substantially deteriorated, and the color of the resin is also rare. influences. Experiments have shown that the flame retardancy of colloidal Sb 2 O 5 is higher than that of non-colloidal Sb 2 O 5 and NaSbO 3 in the same series, and it is the best one among the antimony flame retardants. SbCl 5 used for testing, and cesium alkaloids; NaSbO potassium pyroantimonate and 3 (K 2 H 2 Sb 2 O 7 · 4H 2 O) can be used for identification of sodium ions. SbCl 3 is often used as a catalyst for inorganic and organic chlorination reactions. Sb 2 O 3 is one of the most important of the antimony compound, in addition to the aforementioned use, it can be used as the catalyst petrochemical and synthetic fibers; for the manufacture of mordant, opacifiers; antimony salts used as synthetic starting materials . Used as an additive in the enamel industry to increase the opacity and surface gloss of the glaze. Further, it is an excellent white pigment, titanium white slightly inferior to its hiding power, similar to the lithopone. In the production of titanium dioxide, Sb 2 O 3 can effectively inhibit the photoinduced reaction of titanium white. Utilizing Sb 2 O 3 with good anti-powdering, photostability and flame retardancy, various kinds of antimony-containing titanium dioxide, such as titanium nickel yellow, chemical fiber titanium white, ultrafine rhodium-containing titanium dioxide, etc., have been prepared. Stop Valves are closed by screwing a rubber gasket down onto a seat in the middle of the valve. Pros only use small versions that act as shutoff Valves for fixtures such as sinks and toilets and outdoor sillcocks. Flow is inefficient because of the circuitous route the fluid (water, in most cases) has to follow. It's important to orient the valve in the right direction with the arrow (cast into the side of the valve) aligned with flow direction. That way, water flows against the bottom of the rubber gasket. If the valve is put in backward, the flow will force the gasket away from the top of the valve.
