PROBLEM TO BE SOLVED: To provide a discharged urine processing material for pets having sufficient performance as the discharged urine processing material for pets and capable of retaining strength of solidified block-like objects after absorbing the urine.SOLUTION: The discharged urine processing material for pets comprising active bentonite granulated substances produced by adding and mixing an alkali agent to dioctahedral type smectite clay, includes a crystalline silica component that has a vertex of a [111] plane-derived X-ray diffraction peak in a range of a diffraction angle (2θ)=21.5-22.5° a smectite component that, when absorbing the moisture for 120 hours under atmosphere with relative humidity of 65%, has an X-ray diffraction peak position of a [001] surface thereof by bottom reflection of within a diffraction angle (2θ)=5.2-6.8° and a water-leachable sodium silicate component expressed by a formula (1) of within a range of 0.1-1.0 wt.% with respect to 100 wt.% of active bentonite granulated substances. Formula (1): Na2O*xSiO2 (In the formula, x is the number 0.3-3 as a coefficient representing a mol number of SiO2).COPYRIGHT: (C)2014,JPO&INPIT【課題】 ペット用排尿処理材として十分な性能を備えた上で、吸尿後の固化塊状物の強度を長時間保持できるペット用排尿処理材を提供する。【解決手段】 ジオクタヘドラル型スメクタイト系粘土粒子にアルカリ剤を添加混合して製した活性ベントナイト造粒物からなり、[111]面由来のX線回折ピークの頂点を回折角(2θ)=21.5~22.5°の領域に有する結晶性シリカ成分を含有し、相対湿度65%の雰囲気下で120時間吸湿したときにスメクタイト成分の[001]面の底面反射によるX線回折ピーク位置が回折角(2θ)=5.2~6.8°の領域にあり、式(1)で表される水浸出性ケイ酸ナトリウム成分を活性ベントナイト造粒物100重量%に対して酸化ケイ素換算で0.1~1.0重量%の範囲で含有しているペット用排尿処理材。Na2O・xSiO2 ・・・式(1)(式中、xはSiO2成分のモル数を表す係数で0.3~3の数)【選択図】 図5
