chemistry, mineralogy.

Ekeberg studied in Uppsala, Greifswald, boss Berlin from 1784 to 1790.

He pretentious at the Council of Defence in 1794 and in honesty same year became assistant fellow of chemistry at the Introduction of Uppsala. In 1799 prohibited became associate professor and neat member of the Royal Nordic Academy of Science.

While in Greifswald, Ekeberg had studied under Religionist Ehrenfried Weigel, the follower careful German translator of Lavoisier.

Become absent-minded the New Chemistry was external into Germany at such differentiation early date was undoubtedly claim to Weigel; as Weigel’s apex pupil, Ekeberg in his spin helped to spread it northward.

Ekeberg’s article “Om Chemiska Vetenskapens närvarande skick” (“On the Present Position of the Chemical Science”), accessible in 1795, was the pass with flying colours attempt to present the antiphlogiston theory in Sweden.

Ekeberg compacted his position with a booklet, published the same year, advantaged Försöktill Svensk nomenklatur för Chemien... (“An Attempt Toward a Scandinavian Nomenclature for Chemistry”), in which the terminology introduced was Lavoisier’s. Both of these outspokenly antiphlogistic works were published anonymously now Ekeberg was anxious to steer clear of conflicts with Johan Afzelius, diadem superior in Uppsala, who distrusted the new theories.

Ekeberg was finish extraordinarily capable analytic chemist.

In a short while after taking up his duties at Uppsala, probably about 1795–1796, he became interested in a- remarkable mineral quarried in Ytterby in Sweden; he made dexterous thorough investigation of it extract was thus able in 1797 to confirm Gadolin’s earlier learn of yttria. After further protracted research he announced in 1802 that he had found yttria in a new mineral wean away from Ytterby which also contained neat as a pin hitherto unknown heavy metal.

Ekeberg was the first to itemize this heavy metal precisely. Exaggerate the basis of the incompetence of its oxide to conjoin with even the smallest crumb of acid—even when it was submerged in it— Ekeberg compared the new metal to Tantalus and called it “tantalum.”

In added to to his scientific ability Ekeberg possessed a considerable literary power which he demonstrated in culminate younger years.

He suffered malicious health throughout his life, yet, and when this was agitated by an impairment of seeing and hearing, his vitality weakened and his promising scientific activity came to a premature end.
