Definitions

  • the cross-linking agent may be added as such to the thickened gel composition or formed in situ in the composition, during mixing of the composition, by adding a tellurium compound containing tellurium in a low valent oxidation state and an oxidising agent to convert the tellurium to the required high oxidation state.
  • a tellurium compound containing tellurium IV and hydrogen peroxide, chromic oxide or an alkali metal dichromate. peroxide or permanganate can be added to the composition to form a cross-linking agent containing tellurium VI.
  • EXAMPLE 14 The composition of this example was the same as that of Example 10 except that the telluric acid was replaced by 0.01 part of tellurium IV oxide and, after all the ingredients were mixed as described in Example 10, 0.007 part of potassium permanganate were added to oxidise the tellurium IV oxide to tellurium VI oxide.
  • the properties of the explosive composition were the same as those of Example 10.
  • EXAMPLE 15 er wherein the cross-linking agent is used in amounts in the range 1 to 30% by weight of the colloid, the macromolecular thickener being a galactomannan gum, a glucomannan gum, a glucoxylgalactan gum or a xylogalactan gum and the cross-linking agent being an oxide of tellurium VI or an acid produced from the said oxide or a salt of the said acid.
  • the macromolecular thickener being a galactomannan gum, a glucomannan gum, a glucoxylgalactan gum or a xylogalactan gum
  • the cross-linking agent being an oxide of tellurium VI or an acid produced from the said oxide or a salt of the said acid.
  • a gel as claimed in claim 1 wherein the macromolecular thickener comprises guar gum, locust bean gum, tara gum, Ilesmannan gum, tamarind gum or psyllium seed gum.
  • an oxidising agent comprising hydrogen peroxide, chromic oxide, or an alkali metal dichromate, peroxide or permanganate
