Mixtures with calcium hydride or strontium hydride may explode readily, and interaction of the molten chlorate is, of course, violent. A mixture of syrupy sodium phosphinate ( hypophosphite ) and the powdered chlorate on heating eventually explodes as powerfully as glyceryl nitrate. Calcium phosphinate mixed with the chlorate and quartz detonates (the latter producing friction to initiate the mixture). Dried mixtures of barium phosphinate and the chlorate are very sensitive and highly explosive under the lightest confinement (screwed up in paper).

Rubbing a mixture of calcium (or strontium) hydride with a metal perchlorate in a mortar causes a violent explosion. 

Strontium hydride, SrH2, white solid, formed by heating strontium metal or amalgam in hydrogen gas at 250oC. Is reactive with H20, yielding strontium hydroxide and hydrogen gas. 

To synthesize the 2 -ironcryptates [Mc Fe2(L3)3 ][X] (7-9, n = 1-3), 2,6-pyridinyl-spacered H2L3 (4) was treated with potassium hydride, strontium hydride, or lanthanum(III) chloride and subsequently with iron(III) chloride (Scheme 3) [71-75]. For instance, an X-ray analysis revealed that the cavity of 2 -metallocryptate [Kc Fe2(L3)3 ]PF6 (7) is occupied by a potassium ion, with ninefold coordination to six ligand oxygen atoms and to three pyridine nitrogen... 

Metal hydrides, such as strontium hydride, SrH2, react with water to form hydrogen gas and the corresponding metal hydroxide. 

Strontium is so active it must be stored under kerosene or mineral oil. In this way, the metal does not come into contact with air. In a finely divided or powdered form, strontium catches fire spontaneously and burns vigorously. Strontium is active enough to combine even with hydrogen and nitrogen when heated. The compounds formed are strontium hydride (SrH2) and strontium nitride (Sr3N2). Strontium also reacts with cold water and with acids to release hydrogen gas ... 

BARIUM PERCHLORATE (13465-95-7) A strong oxidizer. Reacts violently with reducing agents, combustibles. Contact with strong acids forms explosive perchloric acid. Contact with isopropyl alcohol forms highly explosive propyl perchlorate. Contact with ammonium compounds, metal powders (especially magnesium, aluminum, sulfur, calcium hydride, and strontium hydride), or sulfur produces friction- and impact-sensitive compounds. Explodes when heated or shocked. 

CHLORINE FLUORIDE OXIDE (7616-94-6) Noncombustible, but many chemical reactions can cause fire and explosions. A powerful oxidizer. Reacts violently with reducing materials, alcohols, alkalis, amines, anilines, benzene, butyl-amine, calcium hydride, calcium acetylide, charcoal, combustible materials, ethers, hydrazine, hydrogen sulfide, finely divided metals, nitric oxide, olefins, orgtinic substances, potassium cyanide, potassium thiocyanate, sodium, strontium hydride, sulfur, sulfur dichloride, sulfuric acid. Incompatible with hydrogen sulfide, potassium thiocyanate, vinylidene chloride. Forms heat-, friction-, and shock-sensitive explosives with calcium hydride, nitrogenous bases, isopropylamine. Attacks some plastics, rubber, and coatings. 

PYRIDINIUM PERCHLORATE (15598-34-2) An explosive. Sensitive to impact, friction, shock, elevated temperatures above 625°F/329°C this temperature may be lowered by the addition of ammonium perchlorate. A powerful oxidizer. Violent reaction with many materials, including reducing agents, alcohols, benzene, calcium hydride, charcoal, combustible materials, ethanol, ethers, fuels, hydrazines, olefins, organic substances, powdered metals, strontium hydride, sulfur, sulfuric acid. 

Silvery-white metal face-centered cubic structure rapidly becomes yellow on exposure to air and assumes an oxide film. The finely divided metal ignites spontaneously in air. d 2.6 mp 757 I bp 1366. E (aq) SF+ /Sr -2.89 V. For a description of reactions which are characteristic of at -kaline earth metals see Calcium. Keep under liquid containing no oxygen. The heated metal combines with hydrogen to form strontium hydride and with nitrogen to form strontium nitride. Strontium salts impart brilliant red color to a flame.
