The origin of gold nanoparticles can be traced back to the 16th century. After Paracelsus created "drinking gold" to treat mental illnesses, nanogold entered the scientific scene.

Due to burning at different temperatures, bismuth oxide can produce three variants: α-body: yellow heavy powdery or monoclinic crystal, melting point 820℃, relative density 8.9, refractive index 1.91. It changes toγat 860℃-body. β-body: gray-black cubic c

Titanium nitride, chemical formula TiN, is a synthetic ceramic material that is extremely hard and nearly as hard as diamond. Commonly used as a coating on titanium alloys, steel, hard alloys and aluminum structures to improve surface properties.

Ding an appropriate amount of nano-SiO2 to ceramic products can not only greatly reduce the brittleness of ceramic products, but also increase the toughness of ceramic products by several or even dozens of times, improve the finish degree significantly.

Bismuth sulfide is a chemical substance with the chemical formula Bi2S3. The molecular weight is 514.15. The general state is brownish yellow powder or crystal.

Zirconium boride is a highly covalent refractory ceramic material with hexagonal crystal structure. ZrB2 is an ultra-high temperature ceramic with a melting point of 3246℃.

Silicon carbide, also known as emery, is made of quartz sand, petroleum coke (or coal coke), wood chips (need to add salt when producing green silicon carbide) and other raw materials through high temperature smelting resistance furnace.

Nanometer titanium dioxide in the photocatalytic decomposition of bacteria to achieve antibacterial effect.

The rapid development of the zirconium industry in China is of long-term strategic significance for the industrial restructuring of the zirconium industry and the sustainable development of zirconium materials on how to utilize zirconium ores with high ef

Titanium carbide chemical formula is TiC molecular weight is 59.89, gray metal-luster crystalline solid, melting point 3140℃, boiling point 4820℃, relative density 4.93. Hardness of 9 to 10.
