The contribution of al-beruniy in developing chemistry

The article describes the work of the great encyclopedic scientist Abu Raykhan al-Beruniy, who made a significant contribution to the development of chemistry. In «Mineralology», Al-Beruniy describes gemstones their types, properties and healing properties in the body. It also provides information on the physicochemical properties of metals such as merrcury, gold, silver, copper, iron, tin and lead. Al-Beruniy also measured the density of metals, as well as human blood, cow's milk, wine and olive oil. The fact that Al-Beruniy gives information about organik substances and minerals in his works indicates that he has great knowledge in the field of chemistry. Since ancient times, mankind has used different types of healing stones and various useful substances. The healing effects of gemstones have been used for different nervous conditions of the body and it is also relevant today. In Mineralogy, mercury is the first in the metal group and its density is determined. It should be noted that for the first time, the density of water is related to temperature and this was determined by this famous scientist. He also determined the density of other fluids: human blood, cow's milk, wine, olive oil and others. Today, such coolants are widely used in chemical technology and in public services; they prevent the appearance of ice on airfield roads and airways. Abu Raykhan al-Beruniy for the first time proposed a method of heating using oxide of organic fertilizers, also to produce ammonia through dry hair distillation.
