(19 alpha)-3,4,5,6,16,17-Hexadehydro-16-(methoxycarbonyl)-19-methyloxayohimbanium - Introduction
Serpentine(Serpentine) is a mineral whose main component is magnesium ferrosilicate. Its properties are as follows:
1. Appearance: Serpentine is brown, green or white, usually with a Serpentine texture, hence the name "Serpentine".
2. Physical properties: Its hardness is relatively low, between 2.5 and 5.5, which can be scratched with a key. Its specific gravity is between 2.2 and 2.9.
3. Chemical properties: Serpentine is a stable mineral that can resist the erosion of acid, but it will gradually dissolve in strong alkaline solution.
Serpentine has a variety of uses, including:
1. Building materials: Serpentine is commonly used as building materials for stone floors, countertops, wall tiles, etc. Its texture is beautiful and is widely used in interior decoration.
2. Gems and decorations: because Serpentine has a unique texture and color, it is often used to make jewelry, ornaments and other decorations.
3. Handicrafts and cultural uses: Serpentine is also often used to carve into various handicrafts and cultural goods, such as statues, spells and gifts.
The preparation of Serpentine is usually formed through geological processes, and its formation process needs to be carried out under high temperature, high pressure and water-bearing conditions.
When using Serpentine, you need to pay attention to the following safety information:
1. Avoid prolonged exposure to the dust environment of Serpentine to avoid injury to the respiratory system caused by inhalation.
2. When processing, engraving or grinding Serpentine, wear appropriate protective equipment, such as masks and goggles, to prevent dust from entering the eyes or mouth.
3. If inhalation or contact with a large amount of Serpentine dust or powder, may cause respiratory tract irritation and skin allergic reactions, should be immediately cleaned and consult medical personnel.
In General, Serpentine is a common mineral with multiple uses, but it needs to be used correctly and safety precautions.
