Modified titanium oxide fine particle powder for molded bodies, composition for molded bodies, and molded body
The invention provides a modified titanium oxide powder which is capable of producing a honeycomb molded body that can be reduced in thickness and weight even if the number of pitches is increased, while having excellent moldability, strength, wear resistance, cracking resistance and the like. The modified titanium oxide fine particle powder which is composed of fine titanium oxide particles, is characterized in that: the fine titanium oxide particles are modified with a modifying agent that is composed of a fatty acid and/or a fatty acid ester; and the content of the modifying agent is within the range of 0.01-1.0% by weight. In the modified titanium oxide fine particle powder, the fatty acid is a saturated fatty acid represented by formula (1) and/or an unsaturated fatty acid represented by formula (2). CnH2n-CO2H (1) Cn'H2n'-2m+1-CO2H (2). In the formulae, n represents an integer of 4-23; n' represents an integer of 13-23; and m represents an integer of 1-6 that is the number of double bonds.
