NOVELTY - A high-temperature binder contains a crystalline material and an amorphous material. The amorphous material is obtained by mixing glass powder material containing 20-50 %mass tellurium oxide, 30-60 %mass lead compound, 1-20 %mass silica, 1-15 %mass phosphorus pentoxide, 1-25 %mass metal oxide (I), 1-20 %mass metal oxide (II), 0.1-10 %mass ammonium nitrate, 0.1-5 %mass niobium oxide, 0.1-5 %mass zinc fluoride and 0.1-10 %mass alkali metal oxide. The lead compound is lead nitrate, lead acetate, lead oxide, lead chloride or lead fluoride.    USE - High-temperature binder is useful for solar cell electrodes.    ADVANTAGE - The high-temperature binder has low thermal expansion coefficient.    DETAILED DESCRIPTION - A high-temperature binder contains a crystalline material and an amorphous material. The amorphous material is obtained by mixing glass powder material containing 20-50 %mass tellurium oxide, 30-60 %mass lead compound, 1-20 %mass silica, 1-15 %mass phosphorus pentoxide, 1-25 %mass metal oxide (I), 1-20 %mass metal oxide (II), 0.1-10 %mass ammonium nitrate, 0.1-5 %mass niobium oxide, 0.1-5 %mass zinc fluoride and 0.1-10 %mass alkali metal oxide. The lead compound is lead nitrate, lead acetate, lead oxide, lead chloride or lead fluoride, the metal oxide (I) is iron(III) oxide, bismuth oxide, erbium oxide, ytterbium(III) oxide, antimony(III) oxide or lanthanum oxide, the metal oxide (II) is magnesium oxide, calcium oxide, barium oxide or zinc oxide and the alkali metal oxide is lithium oxide, sodium oxide or potassium oxide. The crystalline material is modified beta -spodumene, modified beta -cristobalite, modified cordierite, modified aluminum tungstate or titanium pyrophosphate. An INDEPENDENT CLAIM is included for preparation of high-temperature binder involving mixing the raw materials including tellurium oxide, lead compound, silica, phosphorus pentoxide, metal oxide (I), metal oxide (II), ammonium nitrate, niobium oxide, zinc fluoride and alkali metal oxide to form a glass powder and sieving to form amorphous material and mixing amorphous material and crystalline material.
