Xiamen Golden Tungsten New Materials Co., Ltd. will participate in the "4th National Medical Powder Preparation and Physical Property Characterization Technology Summit Forum" held in Country Garden Phoenix Hotel in Taizhou, Jiangsu Province on December 1-2, booth number: A11, welcome new and old customers to visit and guide exchanges.

Main exhibiting products:
1. Japanese Dongcao zirconia grinding beads
TOSOH YTZ Zirconia Grinding Ball
Japan Tojo zirconia grinding beads are made of yttrium stabilized zirconia powder, which has high strength and high wear resistance.
• High density and strength for superior crushing efficiency.
•Smooth surface, good roundness, uniform particle size distribution, can further improve crushing efficiency and dispersion.
• High purity and excellent abrasion resistance minimize unnecessary environmental contamination.
• High abrasion resistance reduces the amount required during shredding processes.
• Excellent dispersibility in wet crushing of high-viscosity, high-specific gravity materials.
• It is resistant to rust and corrosion, and can also be used for water-based processing.

Therefore, zirconia beads are often used in the pharmaceutical industry for processing, because zirconia beads have good stability and easy grinding and processing, so they can be more effectively configured and used in the pharmaceutical industry, and mixed with a variety of different pharmaceutical ingredients to solve the problem of low temperature aging. It is precisely because of this unique performance that zirconia beads can be widely used in the pharmaceutical field.

2. Rare earths
Rare-earth
Rare earth elements are widely found in nature, mainly in the earth's crust, and are also distributed in soil, water, atmosphere and living organisms. Rare earth elements and their compounds have been very popular in the fields of medicine and biochemistry in recent years due to their special physical and chemical properties.
★ Application of rare earths in drugs
1. Anticoagulant effect 2. Burn drug 3. Anti-inflammatory and bactericidal effect 4. Anticancer drug 5. Hypoglycemic effect 6. Anti-arteriosclerosis effect 7. Effect on the digestive system 8. Effect on the nervous system

3. High purity magnesium oxide / high purity magnesium carbonate
Highly-Dispersive Magnesium Oxide/ High Purity Magnesium Carbonate

Magnesium oxide is white monoclinic crystal or amorphous powder. Insoluble in water, insoluble in alcohol, soluble in acid or ammonium salt solution.

Magnesium carbonate is white monoclinic crystalline or amorphous powder. Non-toxic, odorless, stable in air. Slightly soluble in water, the aqueous solution is weakly alkaline.

Magnesium oxide is used in medicine to make antacids, laxatives, neutralize gastric acid, neutralize gastric acid faster, stronger, long-lasting, do not produce carbon dioxide, protect the ulcer surface, so it is mainly used in the production of gastric medicine. It is used in the field of biopharmaceuticals as neutralizing agent, heavy metal adsorbent, anti-caking agent, filter aid, desulfurizer, lead removal, mercury removal, heavy metal removal and decolorization agent, which can also be used in health care products and food as anti-caking agent, antacid, filter aid antibacterial colorant, etc.

Magnesium carbonate is mainly used to neutralize gastric acid to achieve the therapeutic effect, mostly used to treat gastric acid, gastritis, gastric ulcer and other diseases, is widely used in medicine, is a very common medicinal substance.

4. High-purity gallium oxide/high-purity gallium nitrate

Gallium oxide is an inorganic compound white powder, is a wide bandgap semiconductor material, Eg=4.9eV, its conductivity and luminescent properties have long attracted people's attention.

Gallium nitrate is deliquescence. Soluble in water, soluble in absolute ethanol, insoluble in ether. Melting point: 110 °C, boiling point: 200 °C.

Gallium oxide can be made into gallium nitrate for anti-tumor cancer drugs.

Gallium is currently approved in the United States as an intravenous gallium nitrate (Ga(NO3)3·9H20) solution (Ganite) for the treatment of hypercalcemia in malignancy.
