Barium sulphate is not a strong oxidant yet it can give rise to a very violent thermite reaction when it is heated in the presence of a very electropositive metal. This applies to aluminium for which an accident was described. In addition, there was an accident which involved a mixture of this sulphate with red phosphorus although the latter had been previously treated with potassium nitrate and calcium silicide. 

The flammability and explosive hazard of ferrosilicon powder is increased substantially during grinding in a vibratory mill [1], Explosion hazards from air-hydrogen,—acetylene, or—propane mixtures formed during preparation of ferrosilicon containing alkaline earth additives are attributed to contact of barium or magnesium carbide or silicide additive with atmospheric moisture [2],... 

Excess red phosphorus will bum admixed with barium or calcium sulfates if primed at a high temperature with potassium nitrate-calcimn silicide mixture.

Lead tricinate, -> tetracene, -> Barium Nitrate, lead dioxide, antimony trisulfide and calcium silicide. These components meet all requirements currently applied in ammunition technology. SINOXID compositions feature very good chemical stability and storage life, they are abrasion-, erosion- and corrosion-free and ignite propellants with precision. 

A few initiating co lpositions with tetrazene have been described in the En-O clopedia [148]. The most important seems to be Sinonydsatz developed in Germany as a replacement for mercury fulminate mixtures, h proved to be non corrosive and did not erode barrels of firearms. Their composition was lead styphnate 25-55, tetrazene 1.2—5.0, barium nitrate 25—45, lead dioxide 5-10, anlhymony sulphide 0-10, calcium silicide 3-15, powdered glass 0-5%. 

The majority of primers today are based on the synoxyd primer, first introduced in 1928. These utilize lead styphnate as the initiator, antimony sulfide as the fuel and frictionator (a substance that helps to efficiently pass on the energy from compression of the primer cap), and barium nitrate as the oxidizer. Other compounds that may also be present include calcium silicide, acting as a fuel and frictionator gum arabic, a fuel and binder oxidizers such as lead dioxide, lead nitrate, and lead hypo-phosphite ground glass or aluminum powder as frictionators tetrazene, a sensitizer and various other gums and resins as binders.
