  First World War.com - Encyclopedia - Lyddite
Lyddite was a form of high explosive widely used during both the Boer War and First World War, most notably during the latter by the British.
First tested in 1888 Lyddite was considered a relatively 'insensitive' explosive, which meant that it lent itself moderately well to armour piercing shells, given that the substance was less liable to detonate immediately upon impact but would instead be triggered by an impact fuse.
The U.S. high explosive Dunnite, while less powerful than Lyddite, was widely used by U.S. forces on the basis that it was considered even less sensitive than Lyddite and thus less likely to detonate immediately upon impact.

  Armor-piercing shot and shell
Light structures, which, at a short distance from the point of burst, successfully resist lyddite shell and confine the effect of the explosion, may be destroyed by the shower of heavy pieces produced by the burst of a large common shell.
To prevent the premature explosion of the shell, by the friction of the grains of powder on discharge, it is heated and coated internally with a thick lacquer, which on cooling presents a smooth surface.
The base end of lyddite shell is made solid to prevent the possibility of the gas pressure in the gun producing a premature explosion.

In 1911, Krupp did a very progressive thing: They eliminated Lyddite ("Gr.f.88" to them) from their anti-ship projectiles as substituted block TNT (layered and covered in felt and paper and with a thick wooden plug at the upper end of the explosive cavity).
By doing this they eliminated the premature detonation on impact with face-hardened armor that the too-sensitive Lyddite (trinitrophenol or picric acid are alternative chemical names) caused and this allowed delay-action fuzes to be made (the first impact-initiated delay-action fuzes for high-explosive-filled projectiles ever used, to my knowledge).
They also adopted an improved delay-action fuzes based originally on the rather poor German (Krupp) design and later on their own designs, but they also had the problem with the Lyddite boosters that everyone else had who adopted insensitive explosive fillers in AP-type projectiles.

From that time until 1911, when Lyddite was adopted, the cavity was usually left unfilled, as powder exploded too soon on the heavier armour then in use.
Lyddite was adopted for common shell in 1895 and iron was replaced by steel, which had not been used previously as powder would not fragment it properly.
T.N.T. largely replaced Lyddite T.N.T./B.W.X., Amatol and Shellite were tried, the latter being adopted as the standard filling for armour-piercing shell in 1919.

So they were soon abandoned in favor of rifled cannon-firing shells loaded with explosives such as cordite or lyddite.
Lyddite is one of the best known of modern explosives, and is very similar to melinite, used by the French, and shimose, the principal Japanese explosive.
The principal disadvantage of lyddite is that it is intensely acid, so that when moisture is present it attacks lead and other metals, forming explosive compounds which may go off quite unexpectedly.
