Phosphorus - Wikipedia

2019-4-23 · Phosphorus is a chemical element with syol P and atomic nuer 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth. It has a concentration in the Earth''s crust of about one gram per kilogram (compare copper at about 0

Silicone - Wikipedia

2019-4-23 · In making aquariums, manufacturers now commonly use 100% silicone sealant to join glass plates. Glass joints made with silicone sealant can withstand great pressure, making obsolete the original aquarium construction method of angle-iron and putty. This same silicone is used to make hinges in aquarium lids or for minor repairs.

Properties of Tier Wood | Physical and Chemical

Thermal Properties/Temperature Effects: Although wood is an excellent heat insulator, its strength and other properties are affected adversely by exposure for extended periods to temperatures above about 100°F.The coination of high relative humidity or MC and high temperatures, as in un-ventilated attic areas, can have serious effects on roof sheathing materials and structural elements over

Silicon, Chemical Element - structure, water, uses

The largest single use of silicon, however, is in making alloys. The most important silicon alloys are those made with iron and steel, aluminum, and copper. When silicon is produced, in fact, scrap iron and metal is sometimes added to the furnace.
